search tabs

Frequently, I'll send out a search for a file, get a list of results, and then search for the same file again a few moments later. Obviously, since a users connection gets better (supposedly) the longer a user stays on, it is a good idea to search for a file over and over again, until the best results are found.
I've been trying to figure out a way to click on the name tab of the search and have it send out the search again, but I haven't seen this option anywhere. Instead, I have to re-type the search over and over again until I get what I want. It gets a little ridiculous after you've re-typed the same entry 20 times. Could somebody please add a "re-search" button, or a control-click menu selection (right-click for PC users) for these searches.

Thanks
