Current status ActiveGoogle Search (or Google Web Search) is a web search engine owned by Google Inc. Google Search is the
most-used search engine on the World Wide Web,[3] receiving several hundred million queries each day through its
various services.[4]
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").[5]
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 was originally developed by Larry Page and Sergey Brin in 1997.[6] Google Search
provides at least 22 special features beyond the original word-search capability.[7] 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 (70..73),[8] prices, temperatures, money/unit
conversions ("10.5 cm in inches"), calculations ("3*4+sqrt(6)-pi/2"), package tracking, patents, area codes,[7] 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.[9]
The frequency of use of many search terms have reached a volume that they may indicate broader economic, social
and health trends.[10] Data about the frequency of use of search terms on Google (available through Google
Adwords, Google Trends, and Google Insights for Search) have been shown to correlate with flu outbreaks and
