Oleg,
i use TSearch2 with PostgreSQL 7.4.6 and i applied the compoundword patch yesterday. The configuration changed a little bit but the result is the same. I get no compound words. I'm using the locale de_DE with encoding ISO8859-1 for the database.
I think i spell is working correctly except the compound words. If i try
SELECT lexize('de_ispell', 'springt')
i get
lexize {springen,springen}
which seems correct.
But a SELECT lexize('de_ispell', 'Autobahn')
results in
lexize {autobahn}
i would expect {auto,bahn, autobahn}
Hmm, have you checked 'Autobahn' in ispell dictionary ? Does dictionary you used supports 'Z' flag for compound words ?
Autobahn is in the ispell dictionary. What does a ispell dictionary need to support the Z flag???
Try ispell -C Autobahn search 'compound' in 'man ispell' for details. the problem exists only if ispell *does* splits word correctly while tsearch2 doesn't. You should find correct ispell dictionary for german or create it
yourself. You may consult monzilla.net

Timo,
please, check you apply patch for compound word support. What is version of postgresql ? Does ispell dict works for non-compound words ?

Hi there,
i have some troubles with my TSearch2 Installation. I have done this
installation as described in http://www.sai.msu.su/~megera/oddmuse/index.cgi/Tsearch_V2_compound_words <http://www.sai.msu.su/%7Emegera/oddmuse/index.cgi/Tsearch_V2_compound_words> I used the german myspell dictionary from
http://lingucomponent.openoffice.org/spell_dic.html and converted it with
my2ispell
Nearly everything is working fine so far, except two problems:
1.) The stopword-file seems to be ignored: If i try it with SELECT to_tsvector("default_german", "ein Haus") i get "ein":1 "haus":2
ein should be a Stopword for german (and is defined the german.stop file as
well)
2.) The compound words feature doesn"t work too. I have tried a lot of words,
i.e. "Fehlermeldung" with SELECT to_tsvector("default_german", "Fehlermeldung")
i only get
"fehlermeldung":1 but i would expect "fehler" and "meldung" as seperated
entries. Is there anything wrong with the dictonary or my configuration?
My current configuration:
pg_ts_cfg:
default default C default_russian default ru_RU.KOI8-R simple default NULL default_german default de_DE.ISO8859-1 pg_ts_cfgmap:

Can anyone help me?
