I have create an index "My_index"
in tableText.text (Entity.field).

I can create english themes but no greek themes, thus if my text has english and greek words, i take only the english words.

By default, theme generation is for English and French only. That is because basic English and French knowledge bases are included with Oracle. If you add a Greek knowledge base (you will have to find it or build it since it doesn't ship with Oracle) then you should be able to generate themes for your Greek text.

Thank you very much for your answer.

From oracle i take the next direction

To load your language-specific knowledge base, follow these steps:
1.Load your custom thesaurus using ctxload.
2.Set NLS_LANG so that the language portion is the target language. The charset portion must be a single-byte character set.
3.Compile the loaded thesaurus using ctxkbtc:



I can't the steps 1,2.
How can i load my thesaurus?
Specially, how can i Set NLS_LANG so that the language portion is the target language. The charset portion must be a single-byte character set?

I ignored the following:

The charset portion must be a single-byte character set.

I took some Greek terms from the internet (though I have no idea what they said) and created a VERY small thesaurus. I inserted text into a db table, created my index, and generated themes. My small test appeared to work.

Do the same on your system and see if you run into any problems. Again, it appeared to work, but for all I know the output was in wingdings...it looked right to me anyway.

FYI - I'm running 10gR2 beta, so if yours doesn't work and mine does, it may be version too...interesting to find out.
