It depends on how many searches you are making and whether or not there is an API for you to use. I do not think you can do searching with the Google Reader API, unfortunately, but you might want to look into it (and other options, as well). If you cannot use a search API, then you're stuck to searching through the content yourself, in which case you should store it in a temporary database as that will reduce your bandwidth. If you'd like to reduce your bandwidth right away changing the cron to every two hours will cut it in half (from this app, at least).
