Hello, Following on from https://issues.apache.org/jira/browse/LUCENE-3684, does it make sense to expose the startOffset and endOffset from DocsAndPositionsEnum in Spans and TermSpans? I'm writing some highlighter-like code that needs to emit exact offsets for complex boolean queries, and Spans.getSpans seems like the natural place to get them. The relevant patch is pretty tiny.
I also have a patch to add offsets to MemoryIndex, from the same bit of development. Thanks, Alan Woodward
