Han Jiang updated LUCENE-3892:
------------------------------
Attachment: LUCENE-3892-for&pfor-with-javadoc.patch
Add javadocs for previous codes. I'm still not sure about the
IOUtils.closeWhileHandlingException(), I think the exceptions should not be
suppressed when out.close() is called? This patch also makes some minor change
on randomness in testcase.
The Pulsing parts in last patch is not included here, because they doesn't
improve performance significantly.
> Add a useful intblock postings format (eg, FOR, PFOR, PFORDelta,
> Simple9/16/64, etc.)

> On the flex branch we explored a number of possible intblock
> encodings, but for whatever reason never brought them to completion.
> There are still a number of issues opened with patches in different
> states.
> Initial results (based on prototype) were excellent (see
> http://blog.mikemccandless.com/2010/08/lucene-performance-with-pfordelta-codec.html
> ).
> I think this would make a good GSoC project.
