It seems possible to write your own functions to support various
possibilities with text search.
One of the more common thoughts is to have a list of words that you
would like to include, i.e. the opposite of a stop word list.
There are clear indications that indexing too many words is a problem
for both GIN and GIST. If people already know what they'll be looking
for and what they will never be looking for, it seems easier to supply
that list up front, rather than hide it behind lots of hand-crafted
code.
Can we include that functionality now?
