San Francisco (USA Today) -- Google's search is getting more personal by highlighting information drawn from its users' Gmail accounts on its main results page.
Gmail's more than 425 million users already can search within their personal e-mail accounts to find something they need, such as an order from Amazon.com or an airline reservation.
Now, Gmail users who are logged into their accounts will be shown a list of relevant e-mails on Google's main search results page if the correspondence contains a word entered in a search request.
Google is initially testing the feature with just 1 million Gmail users who request access to a "field trial." Gmail users can sign up at http://g.co/searchtrial.
The feature announced Wednesday marks Google's latest attempt to deliver data that people are seeking more quickly as it tries to maintain the dominance of the Internet search engine, the business that generates most of the company's revenue.
The Gmail results show up down the right-side of the search page. You can display them in the main search results area by using "gmail" as a keyword in the search box.
You can click on an icon on the page to withhold Gmail results for a particular search session.
Also Wednesday, Google said voice-based search would soon be available in its mobile apps for Apple's iPhone and iPad. Google submitted the app to Apple last week.
Additionally, Google excutives at a press briefing Wednesday morning demonstrated a new "carousel" display feature that will launch on Thursday. You scroll through as you might through an online photo gallery, flipping across to see images related to your search.
