Yes, but we don't want to duplicate work. UDD currently does not inject stuff like full bug logs or package descriptions, while Enrico as worked on that stuff already and has already a working full text search infrastructure. We really don't want to duplicate/re-implement that elsewhere. Cheers. -- Stefano Zacchiroli -*- PhD in Computer Science \ PostDoc @ Univ.

I know nothing about xapian (neither of postgresql) so sorry if my information are wrong, but reading [1] I noticed that tsearch2[2] was integrated into psql v8.3[3], so that we can do full text search directly from the database[4], since UDD is running on a "PostgreSQL 8.3.1" server.

One of the nice things of UDD is its consistent and relatively well-known interface: SQL queries. Would it be possible, by the means of some Postgres extension written in $PROG_LANG, to query a local Xapian database *from SQL*? There are many full text searches implementations for Postgres, I'm wondering whether we can use an external one based on Xapian. I leave the answer to our beloved Postgres gurus :-) /me just to throwing another idea in the bag. Cheers. -- Stefano Zacchiroli -*- PhD in Computer Science \ PostDoc @ Univ.
