> I dug for a while... the test is a bit sneaky because it compares sorted docs (by score)
across 2 indexes.  Index #1 has no deletions; Index #2 has same docs, but organized into doc
blocks by group, and has some deletions.  In theory (I think) even though the deletions will
cause scores to differ across the two indices, it should not alter the sort order of the docs.
 Here is the explain output of the docs that sorted differently:
> {noformat}
> #1: top hit in the "has deletes doc-block" index (id=239):
> explain: 2.394486 = (MATCH) weight(content:real1 in 292)
> [DFRSimilarity], result of:
>  2.394486 = score(DFRSimilarity, doc=292, freq=1.0), computed from:
>    1.0 = termFreq=1
>    41.944084 = NormalizationH3, computed from:
>      1.0 = tf
>      5.3102274 = avgFieldLength
>      2.56 = len
>    102.829 = BasicModelBE, computed from:
>      41.944084 = tfn
>      880.0 = numberOfDocuments
>      239.0 = totalTermFreq
>    0.023286095 = AfterEffectL, computed from:
>      41.944084 = tfn
> #2: hit in the "no deletes normal index" (id=229)
> ID=229 explain=2.382285 = (MATCH) weight(content:real1 in 225)
