Google Search is a web search engine owned by Google Inc. Google Search is the most-used search engine on the World Wide Web,receiving several hundred million queries each day through its various services.
Google Search was originally developed by Larry Page and Sergey Brin in 1997.
The order of search results on Google’s search-results pages is based, in part, on a priority rank called a PageRank. Google Search provides many options for customized search, using Boolean operators such as: implied “AND” (if several concatenated search terms separated by spaces are given, only pages containing all of them should be returned), exclusion (“-xx”), alternatives (“xx OR yy”), and wildcard (“x * x”).
The main purpose of Google Search is to hunt for text in Web pages, as opposed to other data, such as with Google Image Search. Google Search provides at least 22 special features beyond the original word-search capability. These include synonyms, weather forecasts, time zones, stock quotes, maps, earthquake data, movie showtimes, airports, home listings, and sports scores. There are special features for numbers, including ranges, prices, temperatures, money/unit conversions, calculations, package tracking, patents, area codes, and language translation of displayed pages.
In June 2011, Google introduced “Google Voice Search” and “Search by Image” features for allowing the users to search words by speaking and by giving images.
Google Search is the most popular web search engine and its market share in 2011 was 82.80 %.
