The latest Java (6) does produce a stack trace when am OOM error happens. It
doesn't necessarily point to the source of the leak, though, just at the
unfortunate thing that needed the non-existent memory to do its work.

Do you have a stack trace by any chance, well OOM do not create very
meanful stacktraces but it could help to figure out which error
occures. PermGenSpace belogs to the java heap btw.
The JBoss should actually be able to deal with your redeployment but
in live/production a restart is always requie

process. See http://issues.apache.org/jira/browse/LUCENE-708

I think you're worrying about the wrong thing. There is no "period of
unserviceability" to worry about in closing/reopening a searcher. If, by
saying "searcher", you mean the Lucene IndexSearcher/Reader. If you're
talking about shutting down your service, that's another story.

Hi Renaud,
Maybe you should take a look at the Morphalou project (
http://actarus.atilf.fr/lexiques/morphalou/) it is a database of lemma and
forms in French.
You could extract the data and create a synonym index or something.
Don't hesitate to contact me off list (and in French if needed) for
Non of the stemmers always stem to a valid word. It is not important as
you should be stemming the query as well. The only thing that is
important is that each word always stems to the same base. Many English
words do not stem to real English words with the English stemmer either.
