I asked about that a while ago. It's a problem that hasn't been worked out. You need to search in other ways.

Nic, you're a lot better off going through each category page by page, and seeing what's available, rather than searching by the tags. Sometimes the tag really doesn't describe the design as well as it might, and you could miss something you like very much because you didn't think that 'tag' would apply to that design. Good luck!
