Re: TSearch2 vs. Apache Lucene

Folks,

tsearch2 and Lucene are very different search engines, so it'd be unfair
comparison. If you need full access to metadata and instant indexing
you, probably, find tsearch2 is more suitable then Lucene. But, if
you could live without that features and need to search read only
archives you need Lucene.

Tsearch2 integration into pgsql would be cool, but, I see no problem to
use tsearch2 as an official extension module. After completing our
todo, which we hope will likely  happens for 8.2 release, you could
forget about Lucene and other engines :) We'll be available for developing
in spring and we estimate about three months for our todo, so, it's
really doable.
