Forum OpenACS Q&A: Response to Improving and synchronizing Search in Oracle and Postgresql versions.

The reason it died, IMO, isn't because no one is interested (we should  all be interested) but because it's a large enough task that it needs a champion who will push it forward.

Maybe that should be you? :)  After the new site work is done, of course.  That doesn't mean you have to figure out how to write the code all by yourself or anything like that, of course.

I'd suggest the first thing that needs doing is to build that Oracle service contract implementation and figure out how to hook InterMedia searching up to the new package while not breaking the old sitewide-search package, at least in the near term.
