In a multithread app like web app, a shared IndexSearcher could throw a
AlreadyClosedException when another thread is trying to update the
underlying IndexReader by closing the shared searcher after the index is
updated. Searching over the past discussions on this mailing list, I
found several approaches to solve the problem.
1. use solr
2. use DelayCloseIndexSearcher
3. use LuceneIndexAccessor
the first one is not feasible for us; some people seemed to have
problems with No. 2 and I do not find a lot of discussions around No.3.
I wonder if anyone has good experience on No 2 and 3?
Or do I miss other better solutions?
Thanks for any suggestion/comment!
Jay
