Kevin,
in 8.4 it'd be possible to use prefix search, see our presentation
about GIN at PGCon 2008. For now you can use dict_regexp, which
allows to use perl's regular expressions. Get it from
http://vo.astronet.ru/arxiv/dict_regex.html

Has anyone dealt with the issue of using tsearch2 with statute cites
yet? Do you have a sample dictionary or any tips? We need to confirm
with the users, but I think desired behavior is that a statute cite of
'813.12(1)(am)' should be found on any leading portions -- that is,
any of the following search arguments should find it:
813
813.12
813.12(1)
813.12(1)(am)
On the other hand, a document containing '813.12(1)' (without the
'(am)' should be found by the first three of the above, but not the
last.
This would seem to require using a slightly different dictionary set
to create the tsquery than to create the tsvector. There's no problem
with that, is there?
