You have to log into "My eBay", that's where it shows you what you have bid on, won, sold, etc for the last 30 days. It also has a link there to your "favorite searches", you click on that and all the searches come up. Then you can chose to delete them from there. When I add a favorite search, first I do the search to make sure the desired results are coming up. Then on the results page there is a link "add this search to favorites" or something, that automatically adds it to your list of searches.
