The Hits should only be accessed when its corresponding IndexSearcher is open. Attempting to access the Hits after the searcher is closed may result in above exception.

The most disturbing thing is that this is not mentioned in the Lucene Javadoc, nor in the "Lucene In Action" book. Thus guarantee any newcomer will be hit by the hits issue! (pun intended)
