I've barely begun resurrecting the old bboard search scripts used by photo.net before Oracle (and Context and Intermedia) entered the picture. Slow, but served photo.net for a couple of years, and actually worked.
I've repaired bboard_contains but my laptop doesn't have network access at the moment (working on that, I'm in Boston for three weeks) so I've not updated the CVS tree. I've been sick with something that's suspiciously like the flu, right down to details like 103 degree fevers, so it probably won't be until next week that I get this first cut at a search facility - for bboard only - up and running.
I hope to work on a more comprehensive and more efficient approach for site-wide searching later this summer.
