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.

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
