Michael McCandless updated LUCENE-4986:
---------------------------------------
Attachment: LUCENE-4986.patch
Patch with test case showing the failure, from Reg (I tweaked it a bit to adapt
to trunk APIs).
I think to fix this, the NRT reader should also (only?) track the changeCount
that IndexWriter uses.
> NRT reader doesn't see changes after successful IW.tryDeleteDocument

> Reported by Reg on the java-user list, subject
> "TrackingIndexWriter.tryDeleteDocument(IndexReader, int) vs
> deleteDocuments(Query)":
> When IW.tryDeleteDocument succeeds, it marks the document as deleted in the
> pending BitVector in ReadersAndLiveDocs, but then when the NRT reader checks
> if it's still current by calling IW.nrtIsCurrent, we fail to catch changes to
> the BitVector, resulting in the NRT reader thinking it's current and not
> reopening.
