First of all, my hats off to you for a job well done. I've been very excited about this and I like the way it functions and presents material. In particular, I like that the searched for word/phrase is in orange in the results. Looks great and at the same time serves a purpose. Initially my only suggestion would be to have it say "no results found" when non are. Only because it's a bit hard to tell if it's still "searching" or if it's done and nothing was found. Very cool mk. You should put some easter eggs in there. [edit] or better yet, while it is searching what about one of those animated hub-wheels that appears in the preview boxes?
Thanks. Those are good suggestions. As I said, it's very alpha. One thing I am going to do in short order is to create a search-optimized version of the database to reference. There's a lot that can be done upfront that I am not doing yet. That's one reason it's a bit slow. However, I was often wanting to look for a tag or a user, so for that reason alone, I thought it was worthwhile to push it out.
