Subject [jira] Commented: (LUCENE-503) Contrib: ThaiAnalyzer to enable Thai full-text search in Lucene

Samphan Raruenrom commented on LUCENE-503:

> -It uses the english stop words, does that make sense?

Yes. Thai usually mix English words in Thai text here and there. So English stop words should
apply but this is arguable. I'll consull with the developer community.

> -Could you write some test cases, similar maybe to those for the French analyzer? 

OK. I'm thinking of writing them.

> Thai text don't have space between words. Usually, a dictionary-based algorithm is used
to break string into words. For Lucene to be usable for Thai, an Analyzer that know how to
break Thai words is needed.
> I've implemented such Analyzer, ThaiAnalyzer, using ICU4j DictionaryBasedBreakIterator
for word breaking. I'll upload the code later.

One possible problem is that it requires ICU4j. I don't know whether this is OK.
