Thanks for the advice, for right now I went with the second option of preprocessing the text before passing it to the to_tsquery.
However I would like to see what it would take to get some of the dictionaries available out there to be hooked into the postgres on windows. Does anyone have any pointers or ideas on where I can start to look if I want to compile and add a dictionary to tsearch2 but on windows environment?
Thanks,
Laimis

Yes, we have dict_regex, which was developed by Sergey Karpov, see details
http://lynx.sao.ru/~karpov/software/postgres_dict_regex.html
It uses pcre library and you need to know perl regexps.
