Tsearch2 & Hebrew

From
Yonatan Ben-Nes
Date:

Hello all,


I want to use Tsearch2 for a current project I have but I can't seem to find a way to implement it on hebrew content.

I found that there is an hebrew Ispell project and apparently I can use it as a dictionary but I can't find any hebrew stemmer to work properly with it, or maybe I'm wrong and I can work only with the dictionary?

Any information will be helpful.


Thanks a lot in advance!

I have the same problem since I have an UTF-8 Database of arround
380 GByte (growing 100 MByte per day) in over 60 languages and
can not search in arabic, farsi and hebrew.

It seems, that there is NO solution for those three languages

Hi all,


Well my problem was that I didn't know if Tsearch2 can work on hebrew data without a fitting stemmer, my current solution is to use the 'simple' dictionary so no lexem is returned.
I wonder if there is an hebrew stemmer which I can use but I can't seem to find one, so sadly one of the best features of Tsearch2 isn't working for me.


If I'm wrong please let me know :)


Thanks a lot in advance,

No, I didn't thought that it will be useful if it won't be accompanied by an hebrew stemmer which will work with it... I'm wrong?

ispell and stemmer are doing the same job, so you may use

ispell,simple configuration instead of "ideal"  one: ispell, stemmer

Of course, some words will not recognized and will leave as is.
Also, you may write very simple stemmer using collection of very common
endings.

------------------------- END OF REPLIED MESSAGE -------------------------

One of my two programmers had coded last year stuff in php5 (UNICODE
is now working) to search à la Google in my Database.  I am collecting
international stuff about wars, warcrime and violation of human rights.

My database is text/plain UNICODE and has curently arround 380-390 GB
which I have splited into tables of 10 years...

It seems, there is a problem with BIDI searching.  Russian and chinese
is NO problem.  Many texts are mixed like US-ASCII, arabic and hebrew.

Now if I enter search strings it returns nothing.
Even if I am in psql with multilingual terminal or in pgadmin.

So it can not be a problem with PHP5.

Oh yes, since I have switched to one table per 10 years, tsearch2 do
not want to search my whole Database...  but for tsearch2 I think, I
am looking for a PHP5/PGSQL coder on <www.getacoder.com> since I am
not the master of PHP5 and PGSQL.  (I am more Sysadmin and soldier
then programmer even if I can code stuff)
