Google has taken a major move to integrate Web search and and personal search . Google is doing a "limited field trial" in which it will let some users get results from their Gmail accounts as well when searching on Google .
So when participating users search for “Amazon,†information from their own recent purchase confirmation emails will appear on the right rail. Or, a user could type “my flights†as a search query, and see — directly at the top of their search results — itineraries drawn from their flight confirmation emails.
So , when Gmail users who are logged in do a regular search on Google's main page , relevant e-mails will also be shown , if they contain word corresponding to the search .
Currently Google is testing the feature with just 1 million Gmail users .
