----------------------------------------------

I think it should be fine with this issue itself.

> The UnifiedHighlighter is derived from the PostingsHighlighter, which should 
> be quite obvious to anyone who cares to look at them.  There is no feature in 
> the PH that is not also present in the UH.  The PH is marked as 
> {{lucene.experimental}} so we may remove it in 7.0.  The upgrade path is 
> pretty easy given the API similarity.  By removing the PH, the goal is to 
> ease maintenance.  Some issues lately have been applicable to both of these 
> highlighters which is annoying to apply twice.  In one case I forgot to.  And 
> of course there is user confusion by having both.
> What I propose to do in this issue is move {{CustomSeparatorBreakIterator}} 
> and {{WholeBreakIterator}} out of the {{postingshighlight}} package into the 
> {{uhighlight}} package (or perhaps add a {{common}} or {{util}} should future 
> highlighters need them?).  Then of course remove {{postingshighlight}} 
> package.
