searching and indexing simultaneously...

HI all.

i am newbie to lucene

Do lucene provides any way to do indexing ,searching and deleting simultaneously ..

I hope we could do searching and indexing which means there can be multiple indexreader and only one indexwriter accessing the index..

Could we have two indexwriter working simultaneously...?

Any help is greatly appreciated
Thanks in advance.

regards

Hi,
You are right. There can be multiple indexreaders but only one indexwriter
is advised. 

No, we can not use two indexwriters simultaneously.

As far as I know, the best information about various Lucene concurrency rules, locks and locking is in the Lucene book (e.g. http://www.lucenebook.com/search?query=concurrency+rules ).

The short story is: use 1 IndexSearcher.  Get a new one when you detect index change.  Use 1 IndexWriter.  If you delete documents (via IndexReader), your IndexWriter needs to be closed, and vice versa.
