Multi-tagging

I'll admit it, I'm a fan of incest. And nakadashi. And vanilla. And harem. And a good few other tags, too. I especially like these in some form of combination, such as harem + incest, or forced + humiliation, but I don't want to wade through heaps of unrelated hentai to find one that fits my two-tag wants. So, I suggest to you that we add an ability to find combinations of two, or three, or more, tags. Personally, I don't know how difficult this would be, and such a difficulty is a fully reasonable justification for not doing it, but I would certainly frequently use it and enjoy it.
