You are using probably a Singleton for it, so I suppose you are totally in charge wether it has been closed or not. After closing you just set the Singleton indexWriter instance to null after closing. Then, you open a new one when doing a getInstance on the Singleton. > - What does it happen if users continue adding documents to > the index after > one user action closed it? This obviously should not be possible. You should design your Singleton accordingly. Since you are telling you have very few documents to be indexed, I would rely on synchronized static functions for adding and deleting documents. If OTOH, you have many documents to add, for performance reasons an index queue is adviseable > > Please help!
