Multi-Tag Search?

[Null Parameter]

I had the idea to do searches on multiple tags at one time, instead of the limit of one that the current tag search in vBulletin has.

I have a rough version of this implemented.
Right now you can do two kinds of searches.

Searching multiple tags and ordering them by the most matches.
Searching multiple tags and only showing those that have all of the tags.

I was wondering if other people would have a want/need for this kind of mod, so that I should make it more installable? Or, if by some chance, somebody else has done this already and I don't need to bother?

Thanks,
