Google is an everyday search tool for everything from gossip to technical documents. Although we use it every day, there are a number of search hacks that not everyone knows. These tips can help us find the information we want faster and more accurately, and greatly improve our search efficiency.

Put double quotation marks around the keyword to be searched, and the search engine will return results that match the keyword.
