Overview

Once you've got those indexes in and built, this is the stuff that matters - how to search! This class provides a generic search interface - which you can use to search all your indexed models at once. Most times, you will just want a specific model's results - to search and search_for_ids methods will do the job in exactly the same manner when called from a model.
