Google Search, commonly referred to as Google Web Search or simply Google, is a web search engine developed by Google. It is the most-used search engine on the World Wide Web, handling more than three billion searches each day. As of February 2016, it is the most used search engine in the US with 64.0% market share.

The order of search results returned by Google is based, in part, on a priority rank system called “PageRank”. Google Search also provides many different options for customized search, using symbols to include, exclude, specify or require certain search behavior, and offers specialized interactive experiences, such as flight status and package tracking, weather forecasts, currency, unit and time conversions, word definitions, and more.

The main purpose of Google Search is to hunt for text in publicly accessible documents offered by web servers, as opposed to other data, such as images or data contained in databases. It was originally developed by Larry Page and Sergey Brin in 1997. In June 2011 Google introduced “Google Voice Search” to search for spoken, rather than typed, words. In May 2012 Google introduced a Knowledge Graph semantic search feature in the U.S.
