TSearch2: Problems with compound words and stop 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:

 default_german    host    {simple}
 default_german    hword    {simple}
 default_german    int    {simple}
 default_german    nlhword    {simple}
 default_german    nlpart_hword    {simple}
 default_german    nlword    {simple}
 default_german    part_hword    {simple}
 default_german    sfloat    {simple}
 default_german    uint    {simple}
 default_german    uri    {simple}
 default_german    url    {simple}
 default_german    version    {simple}
 default_german    word    {simple}
 default_german    lpart_hword    {de_ispell,german_snowball}
 default_german    lword    {de_ispell,german_snowball}
 default_german    lhword    {de_ispell,german_snowball}


 pg_ts_dict:

 de_ispell | 17166    |
 DictFile="/usr/local/pgsql/share/contrib/dictonary/german.dict",
 AffFile="/usr/local/pgsql/share/contrib/dictonary/german.aff",
 StopFile="/usr/local/pgsql/share/contrib/dictonary/german.stop"    | 17167 | NULL
 german_snowball    | 17357 | NULL    | 17162 | Snowball stemmer for german




 Can anyone help me?

 regards

 Timo

Timo,

I forward your message to openfts mailing list.
Also, could you specify if locale settings are correct for your
database and what dictionary you have downloaded.

Timo,

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

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}

The new configuration after the compound word patch:

Hmm, have you checked 'Autobahn' in ispell dictionary ? Does dictionary
you used supports 'Z' flag for compound words ?

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

Re: TSearch2: Problems with compound words and stop words

Timo,

take a look into .aff file and search 'compoundwords'.
german ispell file I got from http://j3e.de/ispell/igerman98/ has no
support for compound words: 'compoundwords off'

Norwegian, for example, has:

compoundwords controlled z

compoundmin 4
