I went back and looked at the tree that I actually had, and unfortunately it's considerably more complex (it does stuff like set up search profiles and then refile articles into various special groups, and it's very ugly and not clearly the right way to do things). So it looks like someone trying to implement this would have to start pretty much from scratch. :/ I'll note from experience with things like this that the hard part in making full-text searching acceptably fast will be incremental indexing of each article as it comes in. Many of the existing search engines suck at incremental indexing. -- Russ Allbery (rra@stanford.edu)
