I finally checked the weblog search functionality into the CVS. Thanks to Robert's recent changes with only one text table, it was very easy to implement a search on both stories and comments.

Maybe I'll add partitioning of search results on separate pages today, which could be extended to a generic previous/next navigation framework.

Let me know what other features you'd like to see. There's a lot we can do here, like advanced searches, searches over the whole site instead of just one weblog, etc.
