change the stop words file for tsearch2
How can I change the name of the file with the stop words used by tsearch2?
I tried searching in the pg_ts_* tables, but I didn't find anything.
Moreover, suppose you have a table with (text,ts_vector,boolean)
columns. Do you think it might be possible to use two different files of
stop words, in case the boolean field is true or false?

only dictionaries use stop-words, so check dict_initoption in pg_ts_dict table:
w=# select dict_name,dict_initoption from pg_ts_dict;
dict_name | dict_initoption
--------------------+---------------------------
simple |
en_stem | contrib/english.stop
ru_stem_koi8 | contrib/russian.stop
ru_stem_utf8 | contrib/russian.stop.utf8
ispell_template |
synonym |
thesaurus_template |
btw, did you read tsearch2 documentation ?
Regards,
Oleg
