This is a very big hint to your problem.

I am assuming that your cluster is running created with en_US for the locale,
and that you have set the matching tsearch2 configuration to be your default
(Or curcfg for each process running).

If you look at your config mappings for the "default_english" you will notice
that you have 16 records, as opposed to 19 records like every other
configuration mapping.  From some more in depth observations, I noticed you
are missing entries for the 'lword', 'lhword' and ''lpart_hword'.  That means
that tokens found to be of types 'Latin Words', 'Latin Hyphenated Words' and
'Latin Part Hyphenated Words' are just dropped because you do not have a
configuration mapping set up for them.

This is why only numbers (or other lexem types) would show (They are returned
as lexem_types : int, uint, float, url, etc. for which you have mappings).
Most regular words are simply discarded due to missing entries.  If you fix
your configurations the triggers should work properly.

Your examples worked before, simply because you specified the 'default'
configuration on the insert statement.  Which is not the same as the
'default_english' configuration which is used by the trigger based on your
server encoding (en_US).

I would not recommend this.  The stop file should is most likely on the system
somewhere.  It will change depending on your installation.  Look for
english.stop on the computer(s).  If it is not there, you can grab the one
out of the source distribution and put it wherever you want.  Then just
update the settings to the location you used.


good luck,
