Adrien Grand reopened LUCENE-4734:
----------------------------------


I've encountered several issues recently because of this patch I committed and 
I am considering reverting it. The issue is that it makes the runtime of 
FastVectorHighlighter very bad and this just doesn't work when the text to 
highlight has lots of occurrences of the query terms.

I spent time trying to improve it but I couldn't find a way to make it work 
nicely. I wouldn't feel good to have a release of Lucene out with this patch in 
it so I will revert the patch tomorrow if there is no objection.

> If a proximity phrase query overlaps with any other query term it will not be 
> highlighted.
> Example Text:  A B C D E F G
> Example Queries: 
> "B E"~10 D
> (D will be highlighted instead of "B C D E")
> "B E"~10 "C F"~10
> (nothing will be highlighted)
> This can be traced to the FieldPhraseList constructor's inner while loop. 
> From the first example query, the first TermInfo popped off the stack will be 
> "B". The second TermInfo will be "D" which will not be found in the submap 
> for "B E"~10 and will trigger a failed match.
