David Smiley resolved LUCENE-7620.
----------------------------------
Resolution: Fixed
Thanks for the review feedback Jim & Tim! 6.4 is going to be a great release
for the UnifiedHighlighter. I hope features like this and other improvements
this release get more folks using the UH.

> The original Highlighter includes a {{SimpleFragmenter}} that delineates
> fragments (aka Passages) by a character width. The default is 100 characters.
> It would be great to support something similar for the UnifiedHighlighter.
> It's useful in its own right and of course it helps users transition to the
> UH. I'd like to do it as a wrapper to another BreakIterator -- perhaps a
> sentence one. In this way you get back Passages that are a number of
> sentences so they will look nice instead of breaking mid-way through a
> sentence. And you get some control by specifying a target number of
> characters. This BreakIterator wouldn't be a general purpose
> java.text.BreakIterator since it would assume it's called in a manner exactly
> as the UnifiedHighlighter uses it. It would probably be compatible with the
> PostingsHighlighter too.
> I don't propose doing this by default; besides, it's easy enough to pick your
> BreakIterator config.
