Note that this is some of our oldest code, based on tsearch2 with
PostgreSQL 8.0. Since then, tsearch has been moved into PostgreSQL
core, improved and documented (Chapter 12 of the PostgreSQL 9.1
manual, Full Text Search). Many of the issues may be fixable with
properly configuration (stop word lists etc.), and new facilities may
make it possible to simplify this old code (pluggable parsers etc.)
