Shai Erera commented on LUCENE-3268:
------------------------------------

Ok I found the problem. The test relies on Lucene doc IDs to assert the results. So at first I went for disabling merges (because they removed deleted docs and screwed up the IDs), but that didn't help entirely because for some seeds, a whole segment turned up to be deleted, and thus dropped, screwing up the IDs as well.

So I fixed the test to add a stored field to all the docs that are deleted, and then instead of asserting that the returned docID was not marked for deletion, I assert that the returned document does not contain that field.

I ran the test w/ -Dtests.iter=10000 (10K) and it didn't find any bad seed. Previously it hunted them pretty quickly !

I'll commit a fix shortly to 3x and trunk.

> In general, on both 3.x and trunk, if you run this test with -Dtests.iter=100 it tends to fail 2% of the time.
