Re: Fulltext search configuration

Ok, thank you Oleg.
I have another dictionary package which is a conversion to hunspell aswell:

http://wiki.services.openoffice.org/wiki/Dictionaries#Arabic_.28North_Africa_and_Middle_East.29
(Conversion of Buckwalter's Arabic morphological analyser) 2006-02-08

And running that gives me this error : (again the affix file)

ERROR: wrong affix file format for flag
CONTEXT: line 560 of configuration file "C:/Program
Files/PostgreSQL/8.3/share/tsearch_data/arabic_utf8_alias.affix": "PFX 1013
Y 6
"
