Nik Everett updated LUCENE-5274:
--------------------------------

    Attachment: LUCENE-5274.patch

Change codestyle on MergedIterator changes and TestMergedIterator to match the 
style in the rest of core.  The FVH changes still use the wide style prevalent 
in the FVH code.
Also, sort fewer numbers in TestMergedIterator to make it faster.  The only 
reason I was sorting so many the first time around was to get a good sense of 
what I was doing to the speed by adding the additional conditional.

> I've been messing around with the FastVectorHighlighter and it looks like I 
> can teach it to highlight matches on "child fields".  Like this query:
> foo:scissors foo_exact:running
> would highlight foo like this:
> <em>running</em> with <em>scissors</em>
> Where foo is stored WITH_POSITIONS_OFFSETS and foo_plain is an unstored copy 
> of foo a different analyzer and its own WITH_POSITIONS_OFFSETS.
> This would make queries that perform weighted matches against different 
> analyzers much more convenient to highlight.
> I have working code and test cases but they are hacked into Elasticsearch.  
> I'd love to Lucene-ify if you'll take them.
