Guys, there is a big difference between semi-static index (aspseek) and
incremental indexing of incoming documents (tsearch2). Our approach is
to develop fully automatical searchable mailing list archive with
instant indexing. So, for example, I see my postings about subj.
already in database and *searchable* ! I don't expect aspseek's search
engine at has my recent postings in its index.
OpenFTS has full access to metadata of documents, so we could limit search '
range by date, by list, by authors, so smart user could get reasonable
search performance (relevance is very good, because it based on
proximity). So, different searches for different purposes !
