Michael McCandless updated LUCENE-3769:
---------------------------------------
Attachment: LUCENE-3769.patch
Patch; this is a great simplification of the NRTMgr API, and I think sets it up
for ThingyManager.
But: I had to introduce TrackingIndexWriter, which just wraps an IndexWriter
and tracks the changes made through it (as a generation). Previously
NRTManager did this all itself, but now you may need to share this tracking
across 2 NRTManagers so I had to pull it out...

> NRTManager is hairy now, because the applyDeletes is separately passed
> to ctor, passed to maybeReopen, passed to getSearcherManager, etc.
> I think, instead, you should pass it only to the ctor, and if you have
> some cases needing deletes and others not then you can make two
> NRTManagers. This should be no less efficient than we have today,
> just simpler.
> I think it will also enable NRTManager to subclass ThingyManager
> (LUCENE-3761).
