Power searching is an important part of making use of available data. Definitely useful!
Could you also expose available operators (and their meaning/use) via proc or adp include fragment, so applications that use this feature can have a user-accessible help page about it?
I am looking at the latest tsearch2 frm PG 8.2 which has some new features taht look useful. It was backported to work on 8.1 as well so it might be nice to support that soon in OpenACS 5.3.
