Google just made it better for the loyal users of its Gmail application. Through a blog post on the official Google Docs blog, you can now search mails, sites and docs all withing Gmail. After you enable Gmail Labs tab under Settings, the “Search Mail” button in Gmail will say “Search Mail and Docs” instead, and your search results will include matching documents and sites in addition to email messages.
Google also added the “Did You Mean” functionality to help you in suggesting what you might have meant.
