Has anybody used Java Search Engine?

Has anybody used Java Search Engine? I installed it on my system and configured jse.xml as per my requirements. When I run the program it indexes the folder but doesn't search for the string in sub-foldrs and in files.
Has anybody used java search engine successfully?If yes,please reply to this thread.

I haven't used it, but if your looking for a Java search engine, how about Apache Lucene? you can debug it with lumbermill.

I reied using Apache Lucene but we have to do the indexing,its not done internally. It will slow down the performace a lot.
