Ever navigate away from a site and have trouble duplicating the search you used to find it? Google has come to the rescue again with a handy "History" link on the Google mobile site. You can find old searches, remove items from your history, and even star search items if you're so inclined. The history includes all searches made while signed in with your Google account, not just those from your phone, and mobile searches are designated by a little phone icon.
Search history should be enabled by default; if not, you can select "Settings," then hit "Save Searches" under "Search History" and save your settings. It's not clear whether search history will be made similarly accessible from the desktop site (although you can simply navigate to google.com/history). There may be some kinks to work out, as evidenced by the following screenshot, so share your experience in the comments! [Google Mobile Blog]
