Thank you for you detailed answer. I have learned alot more about this stuff now :)
Your welcome :-)

As I see it accordingly to the results it's between Hunspell and Aspell. My Aspell version is 0.6 released 2006. The Hunspell was released in 2008. 

When I run the Postgres command \dFt I get the following list :
  • ispell 
  • simple
  • snowball
  • synonym
  • thesaurus

So I set up my dictionary with the ispell as a template and Hunspell/Aspell files. Now I just have one decision to make :)

Just another thing: 
If you want to support multiple language dictionaries for a single table, with each row associated to its own dictionary

Not really, since the two languages don't overlap, couldn't I set up two separate dictionaries and index against both on the whole table ? I think that's what Oleg was refering to. Not sure...
Neither am I, so when in doubt, try it out.  And let us know the results.

Thanks for all the help / Moe

Ps. I can't read Arabic so I can't have a look on the files to decide :O

In which case, assuming you do not have access to a friend who is able to read Arabic, either choose the file with the most entries (making assumption that more is better) or take the one that came with the dictionary (assuming that those two will be best matched) or if you still can't decide, flip a coin.  As you can't read Arabic, it is not as if you are in a position to put both files through their paces and test them against a word list, picking the one that gives you the best results for the type of words your text is likely to contain.

Cheers,

Andy
