Gmail has introduced a new search feature which is really cool. I have posted many Advanced search tips earlier. this adds to the same list again.
Here is the screen shot showing this feature.
Click the Show options link and you will see a menu opening in the left side
Once when you see this menu choose the parameters to get the refined result as you wanted. You will also see a new link button appearing at the end of this menu called “Reset options†when you choose any of the other options. Just click on that link to reset any filters.
This is a great feature Google has introduced now. We had to do the advanced search so far, now no more tricky searches.
