Web Search Engine
A search engine is a software system that provides hyperlinks to web pages, and other relevant information on World Wide Web, the Web in response to a user's web query, query. The user enters a query in a web browser or a mobile app, and the search engine results page, search results are typically presented as a list of hyperlinks accompanied by textual summaries and images. Users also have the option of limiting a search to specific types of results, such as images, videos, or news. For a search provider, its software engine, engine is part of a distributed computing system that can encompass many data centers throughout the world. The speed and accuracy of an engine's response to a query are based on a complex system of Search engine indexing, indexing that is continuously updated by automated web crawlers. This can include data mining the Computer file, files and databases stored on web servers, although some content is deep web, not accessible to crawlers. There have been ma ...

The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, ''English articles, a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced .

Web Server
A web server is computer software and underlying Computer hardware, hardware that accepts requests via Hypertext Transfer Protocol, HTTP (the network protocol created to distribute web content) or its secure variant HTTPS. A user agent, commonly a web browser or web crawler, initiates communication by making a request for a web page or other Web Resource, resource using HTTP, and the server (computing), server responds with the content of that resource or an List of HTTP status codes, error message. A web server can also accept and store resources sent from the user agent if configured to do so. The hardware used to run a web server can vary according to the volume of requests that it needs to handle. At the low end of the range are embedded systems, such as a router (computing), router that runs a small web server as its configuration interface. A high-traffic Internet website might handle requests with hundreds of servers that run on racks of high-speed computers. A reso ...

WebCrawler
WebCrawler is a search engine, and one of the oldest surviving search engines on the web today. For many years, it operated as a metasearch engine. WebCrawler was the first web search engine to provide full text search. History Brian Pinkerton first started working on WebCrawler, which was originally a desktop application, on January 27, 1994 at the University of Washington. On March 15, 1994, he generated a list of the top 25 websites. WebCrawler launched on April 21, 1994, with more than 4,000 different websites in its database and on November 14, 1994, WebCrawler served its 1 millionth search query for "nuclear weapons design and research". On December 1, 1994, WebCrawler acquired two sponsors, DealerNet and Starwave, which provided money to keep WebCrawler operating. Starting on October 3, 1995, WebCrawler was fully supported by advertising, but separated the adverts from search results. On June 1, 1995, America Online (AOL) acquired WebCrawler.

World-Wide Web Worm
The World Wide Web Worm (WWWW) was one of the earliest search engines for the World Wide Web (WWW). It was developed in September 1993 by Oliver McBryan at the University of Colorado as a research project. It is claimed by some to be the first search engine, though it was not released until March 1994, by which time a number of other search engines had been made publicly available. The worm created a database of 300,000 multimedia objects which could be obtained or searched for keywords via the WWW. It indexed about 110,000 webpages as of 1994. In contrast to present-day search engines, the WWWW featured support for Perl regular expressions. The website, http://www.cs.colorado.edu/home/mcbryan/WWWW.html, is no longer accessiblearchive. Circa 1997 Goto.com purchased WWWW's technology. McBryan stated in a 2016 podcast that WWWW was an educational project and he never thought of commercializing it like Excite or Yahoo!

JumpStation
JumpStation was the first WWW search engine that behaved, and appeared to the user, the way current web search engines do. It started indexing on 12 December 1993 and was announced on the Mosaic "What's New" webpage on 21 December 1993. It was hosted at the University of Stirling in Scotland. It was written by Jonathon Fletcher, from Scarborough, England, who graduated from the University with a first class honours degree in Computing Science in the summer of 1992Googling was born in Stirling The Scotsman, 15 March 2009 and has subsequently been named "father of the search engine". He was subsequently employed there as a systems administrator. JumpStation's development discontinued when he left the University in late 1994, having failed to get any investors, including the Uni ...

ALIWEB
ALIWEB (Archie-Like Indexing for the Web) is the first Web search engine. First announced in November 1993 by developer Martijn Koster while working at Nexor, and presented in May 1994 at the First International Conference on the World Wide Web at CERN in Geneva, ALIWEB preceded WebCrawler by several months. ALIWEB allows users to submit the locations of index files on their sites which enables the search engine to include webpages and add user-written page descriptions and keywords. This empowers webmasters to define the terms that would lead users to their pages, and also avoided setting bots (''e.g.'' the Wanderer, JumpStation) which used up bandwidth. Martijn Koster, who was also instrumental in the creation of the Robots Exclusion Standard, detailed the background and objectives of ALIWEB with an overview of its functions and framework in the paper he presented at CERN. Koster left Nexor and in the following years development ceased until a new company took over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
W3Catalog
W3 Catalog was an early web search engine, first released on September 2, 1993 by developer Oscar Nierstrasz at the University of Geneva. The engine was initially given the name ''jughead'', but then later renamed. Unlike later search engines, like Aliweb, which attempt to index the web by crawling over the accessible content of web sites, W3 Catalog exploited the fact that many high-quality, manually maintained lists of web resources were already available. W3 Catalog simply mirrored these pages, reformatted the contents into individual entries, and provided a Perl-based front-end to enable dynamic querying. At the time, CGI did not yet exist, so W3 Catalog was implemented as an extension to Tony Sander's Plexus web server, implemented in Perl Perl is a high-level, general-purpose, interpreted, dynamic programming language. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was ...

Search Results
A search engine results page (SERP) is a webpage that is displayed by a search engine in response to a query by a user. The main component of a SERP is the listing of results that are returned by the search engine in response to a keyword query. The results are of two general types: * organic search: retrieved by the search engine's algorithm; * sponsored search: advertisements. The results are normally ranked by relevance to the query. Each result displayed on the ''SERP'' normally includes a title, a link that points to the actual page on the Web, and a short description, known as a snippet, showing where the keywords have matched content within the page for organic results. For sponsored results, the advertiser chooses what to display. A single search query can yield many pages of results. However, in order to avoid overwhelming users, search engines and personal preferences often limit the number of results displayed per page. As a result, subsequent pages may not be a ...
