Nik Everett commented on LUCENE-5274:
-------------------------------------
Hey, forgot to mention that. MockTokenizer seems to throw away the character
after the end of each token even if that character is the valid start to the
next token. This comes up because I wanted to tokenize strings in a simplistic
way to test that the highlighter can handle different tokenizers and it just
wasn't working right. So I "fixed" MockTokenizer but I did it in a pretty
brutal way. I'm happy to move the change to another bug and improve it but
testing the highlighter change without it is a bit painful.

> 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.
