Subject [jira] [Created] (LUCENE-3488) Factor out SearcherManager from NRTManager

Factor out SearcherManager from NRTManager
------------------------------------------

                 Key: LUCENE-3488
                 URL: https://issues.apache.org/jira/browse/LUCENE-3488
             Project: Lucene - Java
          Issue Type: Improvement
    Affects Versions: 3.5, 4.0
            Reporter: Simon Willnauer
             Fix For: 3.5, 4.0


Currently we have NRTManager and SearcherManager while NRTManager contains a big piece of
the code that is already in SearcherManager. Users are kind of forced to use NRTManager if
they want to have SearcherManager goodness with NRT. The integration into NRTManager also
forces you to maintain two instances even if you know you always want deletes. To me NRTManager
tries to do more than necessary and mixes lots of responsibilities ie. handling searchers
and handling indexing generations. NRTManager should use a SearcherManager by aggregation
rather than duplicate a lot of logic. SearcherManager should have a NRT and Directory based
implementation users can simply choose from.
