I was referring in my original post to the code in trunk. What I am after is a "getCommittedReader" method similar to getReader that allows to open (fast) an IndexReader reflecting the latest committed state (or closed state) of the IndexWriter. The problem with the getReader method is the fact that it is tied to the IndexWriter instance.
