It supports multi-field highlighting, and ranks the matches within a document
field. It highlights the extent of the actual

I had to make changes like this to get my own SpanRangeQuery and
SpanWildcardQuery to work properly in the larger context. Adding the rewrite
methods wasn't too hard.

more elegant. I like the use of clone(), and I see now that other rewrite
