It's saved by using "Autocomplete" and is stored in the registry and in the appropriate "index.dat" file. If you want to clear the "SearchMRU" (Most recently used), then you should be able to open Internet Explorer, click on "Tools" in the upper left, choose "Internet Options", and in the "General" tab, click on the "Clear History" button, ....then click on the "Content" tab, then click on the "Autocomplete" tab, then click on the "Clear Forms" button. Make sure to clean out the "Temporary Internet Files" folder and the "Cookies" folder also.
I believe you can also selectively remove items from the saved MRU's in Google. Hover your mouse over an item you want to delete from the drop down box until it highlights and then hit your delete key on keyboard.
Other programs such as Ad-Aware and Spybot will also eliminate usage tracks.
Hope this helps.
