MemoryIndex can now store payloads (
LUCENE-6155), and there's a corresponding boolean flag setter on QueryScorer (used by the default highlighter). We should add a parameter to toggle this. It will only take effect if hl.usePhraseHighlighter=true and the source of the tokens comes from re-analysis. This settings is ignored if the tokens come from term vectors which support payloads already (in Lucene/Solr 5) provided they are there.
I suggest naming this boolean parameter hl.payloads.
