Description
Like you can do with the FVH, it'd be nice to be able combine matches from multiple fields with the postings highlighter.
Note that the postings highlighter doesn't do phrase matching and doesn't use term boosts so some of the FVH's field combining features won't work. It'd be nice to get some of them, though.
