Search engines help Internet users find the information they need. In the search bar, a person enters his query: a search keyword or a collection of keywords. And he chooses from the list the site he likes, which best reflects the essence of the question asked to the search engine. Internet search servers are convenient and modern.
Search Server Overview
It processes hundreds of gigabytes of information and gives the user the necessary sites in a convenient format of the list of found pages. This list may consist of hundreds of thousands of pages where these words occur. From all this you can already find the information you need, this can sometimes be problematic. And sometimes you immediately find the right site with relevant information.
AltaVista search server is the least known search engine in RuNet. It was popular with an English-speaking audience during the launch of the Vista system from Microsoft. It has only five hundred and fifty million pages in its database. Four million articles from 15,000 newsgroups within the Usenet aggregator. And search is available for images and other media files, such as videos and sounds. Issuance by pictures is made in a slightly inconvenient format. They are all displayed with a description of the size when you hover the mouse over the picture.
Open Directory Project - this service is more about directories than search engines. But through it, the search is carried out only on high-quality resources of the Internet. Work for the convenience of users is carried out by about 38 thousand editors who daily select sites for their catalog.
Search engine WebCrawler - the number of search service index is about 1.6 million indexed materials. The project directory has about 100,000 categories, where you can define almost any site. The search engine shares a database with another Internet project called Excite, but this project specializes in entertainment traffic, indexing chats and horoscopes.
Lycos - this server has information about 50 million pages. You are given queries to the search server. You can write, for example: "How to write an article for the site", and the search engine will display the necessary information. They are sorted according to your query. Perhaps you will find the right one among them. The queries to the search server for each search engine are given below.
HotBot - contains information about 55 million pages from all over the Internet. Among them you can find the information you need. For convenience, you can specify the desired geo-location. For example, you are looking for a cafe in a certain city and set the corresponding query. The search engine also searches for sounds, graphics, site scripts, and other non-trivial things that you may need. The server has recently connected to "Uzenet" and the search can also be done there.
Google and Yahoo are giants of search
Search server "Google" (Google) - for the entire time of work, about 2 billion pages have already been indexed, through which content of interest to the user is searched. "Runet" is indexed well, but "Google" did not become better than "Yandex", since it takes into account the individual characteristics of the Russian language, spelling and orthoepy of words when searching.
Search server Yahoo (Yahoo!) - has a developed news service, collected from the media around the world. It has about 3,000,000 links indexed. The service is well structured. It is one of the first in the world. But it did not become as popular as Google.
Metasystems
In addition to classical search engines, there are metasystems that search all systems at once. The results will be presented in a form convenient for you. The Yandex service is the largest in Runet and the first of its kind. After the search engine spread to the CIS countries, since it takes into account the morphology of the language. The Copernic 2001 program has been working for a long time and constantly updates its database from various services. The search can be carried out by categories or by geodata. The issuance can be tied to the area from which the request comes.
There is a free and paid version of the service, which is already used by more than fourteen million people. The server uses Google, Yandex, and others to search.
"Rambler" and "Yandex" - the largest directories of sites
Rambler is a Russian site that provides services for finding the necessary information on the Internet. The search engine is quite young, but has already gained popularity in Russia and the CIS, it has its own catalog and news aggregator, which presents a huge number of Russian-language sites. It is the largest in the CIS, followed by Yandex, which bypasses it in terms of quality. It is quite difficult to get into Yandex for little-known sites. In Rambler, however, registration is free for all portals that meet the conditions for accepting a project into the catalog.
File search
FTP index. It contains information about FTP servers that are used to store and distribute information. But the information is in the form of files.
Filez - with it, you can view more than 100 million files that are in the file search engine index.
If you want to find on the Internet not a list of sites, but something more specific, such as a program or a book, in this case you'd better use special search engines or, at the very least, special features of conventional search engines.
To search for files You can use the FileSearch.ru search engine (http://www.filesearch.ru). This is a search engine that searches among millions of files collected from almost all Russian FTP servers and several thousand foreign servers. The search base is constantly updated (Fig. 1).
If traditional search engines search systems on WWW-servers and HTML-pages by their content, then FileSearch.ru searches on FTP-servers by the names of the files and directories themselves. If you need any program, game, etc., then you will most likely find their description on WWW servers, and you can find and download the desired file using FileSearch.ru.
In addition to files, the system can search for images, as well as MP3 or video files. The principle of operation of the system is similar to the search using conventional search engines.
The metasearch system http://www.metabot.ru can search for a wide variety of files (MP3, video, etc.). First of all, you need to select the desired type of search by setting the appropriate switch to the desired position. Then you should enter a search query. As a result, the program will offer a list of found links.
The Rambler-ftp system (http://ftpsearch.rambler.ru/db/ftpsearch) will help you search for files on FTP servers. Here you can also search for files of a wide variety of formats. System users have access to simple and advanced search.
The service http://ru.findfile.net works on a similar principle, which searches for more than 1900 FTP servers.
Rice. one. The main page of the search engine FileSearch.ru
You can use a simple FTP server search tool at http://ftpsearch.orbita.ru. English-language search engines are located on the sites http://www.ftpplanet.com, http://www.shareware.com.
The Google search engine allows you to perform many types of searches. Some of them can be accessed on the English Google page at http://www.google.com. For example, using the Pictures section, you can set up an image search, News - news search. The list of Google search options is presented on the page at http://www.google.ru/intl/ru/options/.
3. Effective Google Search
Advanced search (in foreign systems - Advanced Search) allows you to get fewer links than a simple one, but at the same time their relevance is significantly increased. Most search engines have this feature. There is a special link on the main page for this, which leads to the advanced search page. In this mode, using special tools, you can set more precise selection criteria and refine the search area. In this case, only the set of criteria is expanded, but the search area in most cases is significantly narrowed.
Advanced Google Search
Let's take a look at some advanced search tools. In the Google search engine, you can set the type of query content on the searched pages. In this case, the following options are possible. - with all words - in this search mode, a list of all indexed pages containing all keywords is formed in random order. At the same time, the probability of receiving results that do not match the search query remains. - with exact phrase - in this search mode, a list of pages containing a phrase that exactly matches the key phrase is compiled, punctuation marks are ignored. Usually, the search for the exact phrase will be carried out if the search query is enclosed in quotation marks. - with any of the words - as a result of the search, a list of all indexed pages containing any of the words of the search query is compiled. Often in this case, the number of received links is huge. Search by any word can be useful in cases where the user is not sure about the correct selection of keywords. For example, if you don't know exactly what a term is called, enter both names. - without words - if you want to exclude some words from the search results, specify them in this field (Fig. 2).
Rice. 2. Google advanced search box
Most search engines in the advanced search options allow you to limit the found links to a number of other options. For example, you can set the search for pages in only one language (Language parameter), limit sites to a certain range of update dates (this is convenient if you need to find, for example, only the newest documents). In addition, you can set the search for documents of a certain type (for example, only HTML, DOC, RTF, PPT or PDF files) - the File Format parameter is intended for this. Many search engines allow you to limit your search to a page fragment. For example, you can specify that the search query phrase can only appear in the page title or in the body, in the address, or anywhere on the page - this can be done using the Mention parameter. Another handy solution available among the advanced search options is the ability to search for a search query phrase on a specific site. This feature is available to all currently known search engines, it allows you to get a list of documents from one site that match the query.
Complex search on Google
Complex search provides for the possibility of using the features of the language of search queries. It is unique in its syntax for each search engine, but its capabilities are similar. Here are the most popular tasks that can be solved with a complex search. - If you want the found links to contain the exact phrase of the search query, then it should be enclosed in quotation marks. - If the found documents should contain several words from the search query, then it is necessary to apply the logical operator AND (AND). When working in Google, it corresponds to the + sign. Thus, the entry book + store in the search string will mean the search for such sites, which included both words of the search query. - If the received links must contain at least one word of the search query, then you must use the OR operator (OR). In Google, you need to specify the word or for this. - If you want to exclude documents with certain words from the resulting list of links, then for this you need to use the logical NOT operator. Google uses the - symbol. The operator does NOT need to be entered after the word separated by a space, together with the optional word. For example, a query like map of Paris -(agency|tour) will find a map, not tours in France. Details of using Google can be found at http://www.google.ru/support/?ctx=web.
Special Forces Commands
Additional Google commands allow you to achieve better results and narrow your search. With their help, you can limit the scope of the search, as well as tell the machine that it does not need to scan all the pages. These commands allow you to control the search on the page itself, indicating which part of it should be searched. These special commands are written before the parameter, and some must be preceded by the symbol -. Consider the following commands. - – allinlinks: Searches only in link titles, not in text or page title, for example – allinlinks ain. - – allintext: Looks inside text on pages, but not links or page titles, eg - allintext:piter. - - allintittle: Shows search results in the title of the page. - - allinurl: Shows pages similar to this template, for example - allinurl:links.php. - cache: finds a copy of a page indexed by Google, even if it is no longer available at the address on the Internet or has changed its content. In other words, this command searches the Google cache. It is useful for viewing pages whose content changes frequently. For example, cache:www.news.com. - - cache:url shows the saved version of this page. - filetype: this command allows you to restrict the search to only files with the given extension. However, be careful, Google takes the parameters of the command too literally, and therefore if you first type filetype:htm, and then filetype:html, then the search results in both cases will be different. Google supports searching in the most popular PPT, XLS and DOC file formats. - - info:url this command will show the page containing links to search options: search on similar pages, backlinks and pages containing the same link. The result is the same as if you enter the address of a web page in the search bar. - – intext: in this case, the search will not take into account page titles and links, but only the text of the page (tag
). This is useful when you are looking for a certain piece of text and you, by and large, do not care what the title of the page is and what links are located there. - – intitle: this command, on the contrary, limits the search to only the title of the page, that is, the content of the tag
. For example, such a command - intitle:first page (there should be no spaces between the command and the parameter) will cause Google to provide links to the first pages of Russian-language online newspapers.</p><p>- - inurl: This command will only search the page address. It is usually used in conjunction with other commands when they want to find a search page. For example, the command - inurl:search will display a list of pages that have the word search in the address. For example search.aol.com or home.netscape.com/home/internet-search.html. - - link: returns a list of pages that contain links to the given site. If you enter, for example, - link:ain.com.ua, you will get a list of pages that link to the ain.com.ua resource. This is simply an indispensable monitoring tool for those who are engaged in the "promotion" of sites. - -- related: With this command you can get a list of pages similar to this one. For example, if you enter - related:lenta.ru, you will get a list of links to other online media. In addition, --related: is a handy tool if you want to know what category Google puts your site in (or vice versa if you want to find authoritative information sites). It is authoritative, because when displaying results, Google sorts them in order of importance, and if you enter, for example, - related: cnn.com, then the most significant publications on similar topics will occupy the first positions among the results: The New York Times, Washington Post, etc. .d - - site: - is probably one of the most frequently used commands in Google. It allows you to restrict the data search to only the specified site.</p><p><b>Google search results page address structure</b></p><p>Information about the structure of the address of the page with search results will help you better understand the principles of using search engines. Here is an example of a typical address: http://www.google.com/search?num=55&hl=en&q=piter. It consists of the following parts: - num=55 - number of results per page. This number can range from 1 to 100. The default value is 10; - hl=en - this parameter sets the Google interface language. In this case it is English, but can be changed to hl=ru (Russian); - q=piter is the request itself. Unfortunately, a person is not able to enter a Russian query in the address bar. Here is how, for example, the word cactus looks like: q=%D0%BA%D0%B0%D0%BA%D1%82%D1%83%D1%81. In addition, you can safely add a few more parameters to the URL: - as-qdr=m1 - indicates the maximum "age" of the found information in months. Values can be from 1 to 12; - safe=on - turns on the filter system, which blocks most of the information of a clear pornographic nature.</p><p><b>Google search on your site</b></p><p>The following listing shows a form that will allow you to search for information on your site. To make it work, place this HTML code on your page and use your address instead of mysite.com. Now visitors will be able to search for information of interest to them on the site using Google. <meta
http-equiv="content-type" content="text/html;
charset=UTF-8">
<form method="get"
action="http://www.google.com/search">
<input

value="Google!">
<input type="hidden"
name="as-sitesearch" value="mysite.com">
<input
type="hidden" name=hl value="en">
</form> In addition, you can modify the form to your liking by adding new parameters. For example, the following line: <input
type="hidden"
name="as-filetype" value="txt">will force Google to search only text documents. You can set a date limit for the searched results by adding the line <input
type="hidden"
name="as-qdr" value="m3">(results three months ago). If you want to find data from six months ago, use m6 instead of m3, if you are looking for information for a year, then replace m3 with the Latin y. The number of results per page controls the parameter <input type=
"hidden" name="num"
value="50">.</p><p><b>Google search by email address</b></p><p>A special Google tool called Google Alerts (website http://www.google.com/alerts) allows you to receive search results at the specified email address. To do this, you need to specify the desired search query, set the type of search (news, Internet search or Google Groups search), as well as specify the frequency and email address. As a result, Google will create emails with new sites that match the search query and send them to your email address.</p><p><b>Personal page on Google</b></p><p>Google personal search is a very convenient tool that allows each user not only to store the necessary data on the Google website, but also to create the best appearance for themselves on the main page of the site, turning it into an up-to-date information resource.</p><p>To use Google personalized search, you must go to http://www.google.com/ig. To use the service, you need to register on Google (you can do it here). However, those who are already registered with Gmail, Froogle, or some other Google service can enter their username and password here. The appearance of this page can be customized. It should also be noted the possibility of working with the history of search queries. By default, the main page contains several blocks, including weather information, latest news, new videos on the YouTube service, etc. (Fig. 3).</p><p><img src='https://i2.wp.com/studfiles.net/html/2706/1154/html_tmkkPlLZyL.Fcs_/img-NJDqJL.png' align="bottom" width="100%" loading=lazy loading=lazy><b>Rice. 3.</b> Google personal page</p><p> Each of these sections can be edited, collapsed, or deleted. To edit, you need to click on the button with the image of a triangle and select the line Edit settings in the menu that appears. You can add other information blocks to display on the main personal search page. To do this, click on the same triangle and execute the You might also like command. As a result, a list of Google services will appear. To add any of them, click on the Add it now button in its description. Services are grouped into sections: News (contains news services), Tools (various.189. tools, such as clocks, calendars, maps, dictionaries, notebooks), Communication (services for communication), etc. After adding a block with Gmail The Google Personal Search page will display the titles of the latest messages received in your Gmail inbox, their sender addresses, and when the email was received. In addition, the service allows you to create an information block on your own and place it on the main page of personal search. To do this, you need to set a request, as a result, Google will search for RSS feeds that match it, and offer to place the block on the Google page. Its content will be the exported news headlines of the found RSS feed. Using the Classic Home link, you can at any time go to the classic view of the Google home page, which will not display all the information blocks listed. However, the most interesting features relate to search when working with a personalized Google service. In this case, the entire history of previous requests to the system is stored on the site, it can be placed on the main page of the service. Use the Web History link to switch to the full-featured mode of using the search history. This page displays a list of all previous requests to the system, indicating the dates of the search, that is, the page is displayed as a personal diary. On the right side of the screen is a calendar of search activity - it highlights the intensity of Google usage in different colors (colors are determined in accordance with the number of requests to the system). As your search history fills up, Google starts grouping search results into topics. On the Web History page, after generating a request, you can choose the type of search - search by personal history of search queries or on the Web. After receiving the result, the query can be ordered by relevance or search date. When searching through personal history, the results are sorted in chronological order, with the most recent searches listed first. Next to each result is a search query and a list of visited sites with an indication of the number of visits. Unnecessary results can be easily removed from the history. In addition, it is possible to temporarily suspend autosave requests and links found in response to them. Equally useful is the ability to display related results related to a specific term, name, or object. To do this, you can use the Related History link. The Web History service also automatically remembers visited pages and subsequently highlights them with color, which greatly simplifies navigation and viewing the links of the resulting list.</p>

<li>General information about the syntax of the query language in search engines.</li>
</ol><h2><span>Search servers</span></h2>
<p>The Internet is growing at a very fast pace, and finding the right information among dozens of millions of documents is becoming increasingly difficult. To search for information, special search servers are used, which contain more or less complete and constantly updated information about Web pages, files and other documents stored on tens of millions of Internet servers.</p>
<p>Different search servers may use different search engines to find, store, and provide information to the user. However, the common thing is that at the time of the user's request, all information about Internet documents is stored in a compact form in the database of the search server.</p>
<p>Available search engines can be divided into three groups:</p>
<p>1) Internet directories;</p>
<p>2) general purpose search engines;</p>
<p>3) specialized search engines;</p>
<p><i>Directory Internet</i> <i>(catalog)</i> is analogous to a subject index in a library: it provides a list of the most important documents on a given topic. Examples of such systems are search servers:</p>
<p>http://www.yahoo.com</p>
<p>http://narod.yandex.ru/rubrics/</p>
<p><i><span>General purpose search engines</span>
</i> allow you to find documents on the World Wide Web by keywords. The principle on which most of these systems are based is that special programs - robots automatically "bypass" WWW servers, read and index all encountered documents, while highlighting the keywords related to this document, and remembering them from the URL of this document in the database. Most search engines also allow the author of new Web pages to enter information into the database himself.</p>
<p>An example of such a search engine is Rambler: http://www.rambler.ru</p>
<p><i><span>Specialized Search</span>
</i> systems allow you to find information located in other information "layers" of the Internet adjacent to the World Wide Web, such as FTP servers. An example of such a system is Lycos: http://ftpsearch.lycos.com</p>
<p>Since information on the Internet is constantly changing, search robots do not always have time to track all these changes. The information stored in the database of search engines may differ from the real state of the Internet, and therefore the user may receive a link to a non-existent or moved document.</p>
<p>The interface of search engines is approximately the same. The search engine home page contains a list of sections that refine the search scope and a search field. In the search box, the user can enter keywords to search for the document, that is, words that the user thinks identify the document.</p>
<p><b>How to find an address</b><b>URL</b><b>)?
</b></p>
<p>There are several ways. The easiest way is to see domain names in various promotional materials. At present, any self-respecting company, including any publishing house of books, magazines, editorial offices of TV channels, has its own address on the Internet and usually indicates it on packaging, in books, magazines, on the air of television programs. As a rule, a short address is indicated, consisting only of a domain name, for example: http://www. life. com. ua. Enter such an address in the address bar and walk around the site.</p>
<p>But what if the address is completely unknown? To do this, we turn to URL storages, to special search engines. <b>Search engines</b>(search directories, search servers) are made in the form of Web pages, but these pages contain not information as such, but annotated links to other resources (pages, sites).</p>
<p>To call a search engine, you must specify its address in the address bar of Internet Explorer. There are a lot of search engines on the Internet today. The table below lists only the most popular search engines.</p>

The first step in a search engine is <b>information indexing</b> located on the Internet. <i>Network robot</i> The search engine views a huge number of pages and enters the addresses and summary of these pages into its database, more precisely into <span>search index</span>. Site owners will be very happy if their site is viewed by a network robot. In order for the robot to necessarily view the site and add it to the search index, the owners themselves register their sites in the search engine (usually in several search engines). The process of entering the address and description of the page in the search engine is called <b>indexing</b>. The second stage of the search system is the issuance of accumulated and selected, sorted and classified information at the request of users.</p>
<h2><span>Keyword search</span></h2>
<p>The simplest and most effective search is the search by <b>keywords</b>. Search engines do this. If, for example, you need information about rented accommodation, then you should enter the following key phrase in the search engine search bar:</p>
<p>As a result, the search engine will offer a list of the most relevant sites for this query.</p>
<p>Let's connect to the Internet, open Internet Explorer and enter the address of the search engine in the address bar: http://www.yandex.ru. We will understand in detail the rules for searching for keywords in the search engine. <b>Yandex</b>. In other systems, these rules may differ, but the basic provisions will be identical.</p>
<p>The main search algorithm is as follows:</p>
<p>1. enter keywords in <b>request field</b></p>
<p>2. press the button <b>Find</b>.</p>
<p>After pressing the button <b>Find</b>, Yandex will display <b>link list</b> on the documents that most closely match the request.</p>
<h2><span>Query language syntax</span></h2>
<p>In system <b>Yandex</b> there is a special <b>query language</b>, which is more difficult to use than the advanced search form, but can provide the best results. <b>Search query</b> entered in the search field, it may contain keywords and <span>Special symbols</span>, allowing you to establish relationships between these words and enter additional parameters. Some of these symbols are presented in the following table.</p>

<p>Checking a nickname for dozens of services at a time, counting reposts on Facebook and visualizing Twitter account connections. <br></p>
<p>Social media content analysis is a hot topic among startups. There are more and more services for searching for posts and people every year. But many of them either disappear quickly, are available in an unfinished state, or are expensive to use.</p>
<p>This material contains those few of them that allow you to quickly and free of charge get really useful or just interesting information.</p>
<h2>1. Profile search</h2>
<p>Search system <a rel="noopener noreferrer nofollow">snitch</a> allows you to search for a person's profiles in four dozen services, including the websites of the world's leading universities and the US criminal database:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/snitch_name.jpg' width="100%" loading=lazy loading=lazy></p>
<p>Unfortunately, some of the sites for which you can check the boxes no longer work. For example, Google Uncle Sam, closed 5 years ago. But despite this and other jambs, Snitch is a useful service that allows you to significantly save time when searching for information about a person.</p>
<p>If for some service instead of blocks with search results a blank screen is displayed, then to view them you need to follow the link <b>Open a new window</b>:<br><br><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/snitch_tip.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>2. Search for hashtags</h2>
<p>It is very easy to use. It is necessary to drive the desired hashtag into the search form and in a second a list of recent entries marked by it in six social networks will appear:</p>
<p><img src='https://i0.wp.com/iphones.ru/wp-content/uploads/2016/03/tagboard.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>3. Analysis of recent tweets</h2>
<p>The service allows you to get a list of the last hundred tweets containing the search word, hashtag or account name. And also to find out some analytical information about the people who made these tweets and the time of their creation:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/tweetreach.jpg' width="100%" loading=lazy loading=lazy></p>
<p>Let's say you want to find out which user caused an unusually high number of clicks to an article from Twitter. We look at the last 100 tweets and see which of the people who mentioned the original concept has the most followers:</p>
<p><img src='https://i1.wp.com/iphones.ru/wp-content/uploads/2016/03/top_contributors.jpg' width="100%" loading=lazy loading=lazy></p>
<p>A large number of tweets are available to owners of a paid subscription for analysis:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/tweet_reach_pro.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>4. Twitter account analysis</h2>
<p>On the <a rel="noopener noreferrer nofollow">Mention app</a> you can enter the account name and get information about it (who retweets most often, what hashtags it uses, etc.) in the form of a link diagram:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/mentionmapp.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>5. Search for tweets on the map</h2>
<p>If you click anywhere on the map on , you can read the latest tweets made nearby:</p>
<p><img src='https://i0.wp.com/iphones.ru/wp-content/uploads/2016/03/geochirp.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>6. The number of mentions in social networks</h2>
<p><a rel="noopener noreferrer nofollow">Sharedcount</a> helps to evaluate the popularity of an article/site in social networks. You drive in the URL and in a couple of seconds there are statistics of mentions on Facebook, Google+, Pinterest, LinkedIn and Stumble Upon:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/shared_count.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>7. Search forums</h2>
<p><a rel="noopener noreferrer nofollow">boardreader</a> is a search engine for forums and bulletin boards:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/bordreader.jpg' width="100%" loading=lazy loading=lazy></p>
<p><img src='https://i1.wp.com/iphones.ru/wp-content/uploads/2016/03/russian_fenomen.jpg' width="100%" loading=lazy loading=lazy></p>
<p>An assessment of the scale of the disaster showed that there are almost 4 responses on this portal per inhabitant of Russia.</p>
<h2>8. We break through the login on social networks</h2>
<p>Go to knowem.com and type in the person's nickname. In response, we receive information about which services it is registered on:</p>
<p><img src='https://i2.wp.com/iphones.ru/wp-content/uploads/2016/03/knowmen.jpg' width="100%" loading=lazy loading=lazy></p>
<h2>9. Determine the person's name by email</h2>
<p>If you are still looking for people by entering their email addresses into Google, then you should give up this method. After all, there is pipl.com. You drive in an email (nickname) and get a list of profiles in social networks:</p>
<p><img src='https://i1.wp.com/iphones.ru/wp-content/uploads/2016/03/pipl.jpg' width="100%" loading=lazy loading=lazy></p>
<p>The information is not always accurate and complete, but the service is exceptionally useful.</p>
<p>That's all. It was worth talking about Socialmention (unfinished review analysis), Yomapic (search for photos from VK and Instagram on the map) and yandex.</p>
<h3>Specialized Search Engines</h3>
<p>Specialized search engines allow you to search for information in other information "layers" of the Internet: file archive servers, mail servers, etc.</p>
<p><b>File search.</b> There are two types of specialized search engines for searching files on file archive servers: database-based search engines and file directories. To search for a file in the system using the database, it is enough to enter the file name in the search field and the search engine will return the URLs of the storage locations of this file.</p>
<p>The database of the Russian file search system (http://www.filesearch.ru) contains information about 6 million files located on two thousand file archive servers in the Russian part of the Internet.</p>
<p>Let us first search for the ICQ interactive communication program file in the database of the Russian file search system.</p>
<p><b>File search</b></p>
<p>1. Open the www.filesearch.ru server in a browser. In the search field, enter the file name, for example ICQ. Other fields of the search form allow you to refine the search conditions, but they are optional.</p>
<p>If the file name is unknown, but its purpose is known (for example, a driver), then you can use the thematic catalog of drivers.</p>
<p>3. To search for, for example, a printer driver, on the home page of a search engine, click on the link <i>Drivers</i>.</p>
<p>Then select the desired type of printer in the hierarchical directory tree and activate the link to it.</p>
<p>A list of file archive server URLs will be displayed from where the required driver can be downloaded.</p>
<table align="center"><tr><td><img src='https://i0.wp.com/5byte.ru/11/images/komtehn55.gif' height="625" width="400" loading=lazy loading=lazy></td>
</tr></table><p><b>Search for email addresses.</b> Specialized search engines allow you to search for an email address by the name of a person or, conversely, the name of the person who owns a particular email address. An example of such a system is the WhoWhere? (WhoWhere?), located at: http://www.whowhere.com.</p>
<p><b>Practical tasks</b></p>
