["Mark Miller (JIRA)" <ji...@apache.org>]

Mark Miller commented on LUCENE-794:
------------------------------------

There are two highlighting modes: highlight entire spans or highlight first and last word of each span. For the highlight first and last word of span it would probably be better to change QuerySpansExtractor.getSpansFromPhraseQuery so that it creates a series of near spans instead of a single near span with multiple clauses.
