We need independent time & geo searches as well. The indexes are vastly smaller in Solr. We use PostgreSQL extensively and prefer it, so it's not a matter of simply wanting to use something different.
That's very interesting. Could you share your story with the mailing list pgsql-hackers a little bit? The guys who work on indexing are quite active on those lists.
Also, there's some new thing I don't understand super well, sp-gist, do you have any thoughts on that?
