The current tsearch parser is a state machine which does clunky mode switches to handle special cases like you describe. If you're looking at doing very much in there, you might want to consider a rewrite to something based on regular expressions. See discussion in these threads: http://archives.postgresql.org/message-id/[email protected] http://archives.postgresql.org/message-id/[email protected] That was actually at the top of my personal PostgreSQL TODO list (after my current project is wrapped up), but I wouldn't complain if someone else wanted to take it. :-) -Kevin
