Hi Mohamed.
I don't know where you get the dictionary - I unsuccessfully tried the OpenOffice one by myself (the Ayaspell one), and I had no arabic stopwords file.
Renaming the file is supposed to be enough (I did it successfully for Thailandese dictionary) - the ".aff'" file becoming the ".affix" one.
When I tried to create the dictionary:
CREATE TEXT SEARCH DICTIONARY ar_ispell (
TEMPLATE = ispell,
DictFile = ar_utf8,
AffFile = ar_utf8,
StopWords = english
);
I had an error:
ERREUR: mauvais format de fichier affixe pour le drapeau
CONTEXTE : ligne 42 du fichier de configuration « /usr/share/pgsql/tsearch_data/ar_utf8.affix » : « PFX Aa Y 40
(which means Bad format of Affix file for flag, line 42 of configuration file)
Do you have an error when creating your dictionary?

I have ran into some problems here.
I am trying to implement arabic fulltext search on three columns.
To create a dictionary I have a hunspell dictionary and and arabic stop file.
CREATE TEXT SEARCH DICTIONARY hunspell_dic (
TEMPLATE = ispell,
DictFile = hunarabic,
AffFile = hunarabic,
StopWords = arabic
);
1) The problem is that the hunspell contains a .dic and a .aff file but the configuration requeries a .dict and .affix file. I have tried to change the endings but with no success.
2) ts_lexize('hunspell_dic', 'ARABIC WORD') returns nothing
3) How can I convert my .dic and .aff to valid .dict and .affix ?
4) I have read that when using dictionaries, if a word is not recognized by any dictionary it will not be indexed. I find that troublesome. I would like everything but the stop words to be indexed. I guess this might be a step that I am not ready for yet, but just wanted to put it out there.
Also I would like to know how the process of the fulltext search implementation looks like, from config to search.
Create dictionary, then a text configuration, add dic to configuration, index columns with gin or gist ...
How does a search look like? Does it match against the gin/gist index. Have that index been built up using the dictionary/configuration, or is the dictionary only used on search frases?
