Google has announced an improved Gmail search by improving the autocomplete predictions you see when you search in Gmail, reports the Official Google Blog.
“Now when you type something into the Gmail search box, the autocomplete predictions will be tailored to the content in your email, so you can save time and get the information you want faster than ever before. For example, you might now get lax reservation or lax united as predictions after typing “lax” if you have received an email with a flight confirmation for your trip to Los Angeles in your inbox recently.”

We will be rolling out improved autocomplete in English over the next few days and will follow with more languages over the next few months. While initially improved autocomplete will not be available for Google Apps customers, we plan to bring this feature to Apps domains in the future.
