[jira] Commented: (LUCENE-503) Contrib: ThaiAnalyzer to enable Thai
full-text search in Lucene
[ http://issues.apache.org/jira/browse/LUCENE-503?page=comments#action_12374136 ]
Samphan Raruenrom commented on LUCENE-503:
------------------------------------------
I've changed the code to use java.text.BreakIterator instead of ICU4j to remove the dependency on ICU4j. The ThaiAnayzer is tested intensively by several groups of developers in at least two production systems (by To-Be-One Technology, who support the development) so it is quite stable. The code is rather small cause I try to make it as efficient and easy to read as possible. It's tested in Lucece 1.4 and lately in Lucene 1.9.1.

> Key: LUCENE-503
> URL: http://issues.apache.org/jira/browse/LUCENE-503
> Project: Lucene - Java
> Type: New Feature
> Components: Analysis
> Versions: 1.4
> Reporter: Samphan Raruenrom
> Attachments: ThaiAnalyzer.java, ThaiWordFilter.java
>
> 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.
> I'm normally a C++ programmer and very new to Java. Please review the code for any problem. One possible problem is that it requires ICU4j. I don't know whether this is OK.
