Otis Gospodnetic commented on SOLR-553:
---------------------------------------

For cross-reference - SOLR-575 will address merging of highlighted tokens that 
are part of a phrase.

As for the direction to take with integrating the new phrase highlighting 
support, I think the support for proper
highlighting of *pure phrase* queries should be added to DefaultSolrHighlighter 
(DSH) and enabled via useSpanScorer.
DSH could do query instanceof PhraseQuery and run the new code if useSS is on.
Sounds reasonable?

Note that I highlighted (eh) *pure phrase*, as it seems that LUCENE-794 doesn't 
fix cases where we have a phrase that
is a part of a BooleanQuery (e.g. foo AND bar OR "peanut butter")

Patch coming tomorrow...

> Say we search for the band "I Love You But I've Chosen Darkness"
> .../selectrows=100&q=%22I%20Love%20You%20But%20I\'ve%20Chosen%20Darkness%22&fq=type:html&hl=true&hl.fl=content&hl.fragsize=500&hl.snippets=5&hl.simple.pre=%3Cspan%3E&hl.simple.post=%3C/span%3E
> The highlight returns a snippet that does have the name altogether:
> Lights (Live) : <span>I</span> <span>Love</span> <span>You</span> But 
> <span>I've</span> <span>Chosen</span> <span>Darkness</span> :
> But also returns unrelated snips from the same page:
> Black Francis Shop "<span>I</span> Think <span>I</span> <span>Love</span> 
> <span>You</span>"
> A correct highlighter should not return snippets that do not match the phrase 
> exactly.
> LUCENE-794 (not yet committed, but seems to be ready) fixes up the problem 
> from the Lucene end. Solr should get it too.
