Jens,
have you tried german compound dictionary from
http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/

Hey,
thanks for your answer.
First I checked the links in the tsearch_data directory
de_de.affix, and de_de.dict are symlinks to the corresponding files in
/var/cache/postgresql/dicts/
Then I recreated them by using pg_updatedicts.
This is an extract of the de_de.affix file:
# this is the affix file of the de_DE Hunspell dictionary
# derived from the igerman98 dictionary

I cannot find "compoundwords controlled z" there, so I manually added it.

compoundwords controlled z

Then I restarted PostgreSQL.
Now I get an error:
SELECT * FROM ts_debug('Schokoladenfabrik');
FEHLER: falsches Affixdateiformat f?r Flag
CONTEXT: Zeile 18 in Konfigurationsdatei
?/usr/share/postgresql/8.4/tsearch_data/de_de.affix?: ?PFX U Y 1
?
SQL-Funktion ?ts_debug? Anweisung 1
SQL-Funktion ?ts_debug? Anweisung 1
Which means:
ERROR: wrong Affixfileformat for flag
CONTEXT: Line 18 in Configuration ...
If I add
COMPOUNDFLAG Z
ONLYINCOMPOUND L
instead of "compoundwords controlled z"
I didn't get an error:
SELECT * FROM ts_debug('Schokoladenfabrik');
alias | description | token |
dictionaries | dictionary | lexemes
-----------+-----------------+-------------------+-------------------------------+-------------+-------------------
asciiword | Word, all ASCII | Schokoladenfabrik |
{german_hunspell,german_stem} | german_stem | {schokoladenfabr}
(1 row)
But it seems that the hunspell dictionary is not working for compound words.
Maybe pg_updatedicts has a bug and generates affix files in the wrong format?

Jens,
could you check affix file for
compoundwords controlled z
also, can you provide link to dictionary files, so we can check if they
supported, since we have only rudiment support of hunspell.
btw,it'd be nice to have output from ts_debug() to make sure dictionaries
actually used.
Oleg
Regards,
Oleg
