Maps & Downloads Section Request

I noticed that when trying to search through the maps & downloads section that when you type in something simple like "pl_" or "rc" that the search always comes back with no results. I am wondering as to why it does this and how come we can't search by release type or map type. I really don't want to have to sort through all of the beta1's or alpha9's in order to find some mostly completed maps. Do you think that this would be something that could easily be fixed or would there be no way of implementing a feature like that into the search options?

Cool, guess I'm the only one that thought this would be useful. :/
