> Included are the following improvements/fixes:
> * Improving the unit test case.
> * Performance fix that stops the reading of ALL lucene segments over and again for each
stats collector.
> ** The AtomicReaderContext that refers to the "current " segment is reused.
> ** This fix shows an improvement of about 25% in query time for a dataset of ~10M (=9.8M)
records.
> ** Given the nature of the fix, the improvement should get better as the dataset increases.
