Mohamed,
comment line in ar.affix
#FLAG long
and creation of ispell dictionary will work.
This is temp, solution.
Teodor is working on fixing affix autorecognizing.
I can't say anything about testing, since somebody should provide
first test case. I don't know how to type arabic :)

Oleg, like I mentioned earlier. I have a different .affix file that I got
from Andrew with the stop file and I get no errors creating the dictionary
using that one but I get nothing out from ts_lexize.
The size on that one is : 406,219 bytes
And the size on the hunspell one (first) : 406,229 bytes
Little to close, don't you think ?
It might be that the arabic hunspell (ayaspell) affix file is damaged on
some lines and I got the fixed one from Andrew.
Just wanted to let you know.

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

Mohamed,
We are looking on the problem.

No, I don't. But the ts_lexize don't return anything so I figured there
must
be an error somehow.
I think we are using the same dictionary + that I am using the stopwords
file and a different affix file, because using the hunspell (ayaspell)
.aff
gives me this error :
ERROR: wrong affix file format for flag

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?

Mohamed a ?crit :
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?
