Yes, I'm using a solution quite similar to this one. :) But when I read the Lucene 2.3 IndexReader.java code and javadoc, I see they have added a synchronous reference-counter to IndexReader and when it drops to zero, this instance will automatically call doClose() to clean, but the manipulator methods of this counter is marked as `protected'. I thought of extending FilterIndexReader to use the inherited counter manipulator. Has anyone tried this way?
