Shai Erera closed LUCENE-445.
-----------------------------

    Resolution: Not A Problem

Long inactivity. Plus, Lucene in Action 2nd Edition includes an example of SearcherManager which achieves exactly what's proposed here, in a safer way. If we want to commit something like that to Lucene, we should commit SearcherManager or something similar.

> Implements search over a single IndexReader, but remains open even if close() is called. This way it can be shared by 
> multiple objects that need to search the index without being aware of the keep-the-index-open-until-it-changes logic.
> Usage is described in the javadoc.
