If you are getting errors while searching and at the same either adding or
deleting documents, chances are you are not using the API correctly and
following the concurrency rules (described many times on this list). Yo ucan
search and modify your index at the same time. Adding and deleting documents
is best done in batches (e.g. run your deletions first, close IndexReader that
did deletions (could be the same one that is used for searching), open
IndexWriter, add documents, close writer, re-open IndexSearcher/Reader for
searching so your changes are visible).

Hi,
check out this nice patch, it could be useful for your use case:
http://issues.apache.org/jira/browse/LUCENE-565
http://www.gossamer-threads.com/lists/lucene/java-dev/35317
It provides better performance when you have a big number of
update/delete operations.
