Han Jiang commented on LUCENE-3892:
-----------------------------------
Ah, yes, I forgot to use -Dtests.postingsformat...I can see the errors
now.

TestDemo makes a nice TestMin... I usually start with TestDemo when
testing scary new code, and then it's a huge milestone once TestDemo
passes
{quote}
Hmm, that means I should remove TestMin.java? This testcase works fine
for the patch.

We should definitely cutover to BlockTree terms dict (I would upgrade
that TODO to a nocommit!).
{quote}
I'm not quite familiar with these sign stuff, shall I change all the
"TODO" sign into "nocommit"? Are the signs related to documentation,
or just marked to remember not to commit current codes?
> Add a useful intblock postings format (eg, FOR, PFOR, PFORDelta,

> 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.
