I already read this but I don't know how to solve my problems with this
information.

SELECT ts_lexize('english_ispell','guitar');
{guitar}
(1 line)

SELECT ts_lexize('english_ispell','bank');
{bank}
(1 line)

SELECT ts_debug('english_ispell','bank');
(asciiword,"Word, all
ASCII",bank,"{english_ispell,english_stem}",english_ispell,{bank})
(1 line)

SELECT plainto_tsquery('english_ispell','bank');
'bank'
(1 line)

It would be very nice if you (or anyone else) could provide me with
concrete instructions or any howto. What can I do to find the error in
my setup? What output should I expect from the above comments if
everything worked correctly?

Thanks,
