[TYPO3-english] Indexed Search with Thai language - No indexing of Thai words

[Markus Kobligk]

Hi,

we have a website with Thai language, everything runs with utf8 and the 
words and characters are shown correctly in the frontend.
On a test page we have some Thai words and sentences with some englisch 
words wihtin.

When the page is rendered in frontend only the englisch words of that page 
are indexed :-(

When i click on "Info" and show the search index of that page the colujmn 
"Content" shows all the thai words from that page but the column "Words" 
only shows the english words from that page and therefore indexed search 
doesn't find any thai words.

Has anyone ever had the same problem and solved it?
Is this just a missing configuration issue?

What can I do?

Greets,
Markus
