Search bar at the library

A search bar ar the library would really Help. Now, I do not know how things are coded exactly but we could make a tag system. When searching for something (e.g. a spell) that you don't know the name but you know the effect for example, you might have to search for a long time, checking every spell on the list. We could mark trivial words for each entry (I know it's tiring but if needed I volunteer to help) and the search bar will be based on that. For example: Say I'm searching for Expelliarmus but I don't remember the name. We could put certain tags to the entry (e.g. spell, duel, disarm, charm, etc etc) so when the person searches they can at least limit the range of information found. I hope that makes sense to you, it kind of does in my mind. I don't know if it's possible though. Hope it works!
