I'm using ES2.0 and have a field mapped with "term_vector": "with_positions_offsets". Using a "span_multi" query, I get no highlighting information back when using "fvh". However, forcing the highlighter to "plain" works. Is this an expected limitation of FVH?
The reference documentation provides a warning for the "postings" highlighter that it may not work with certain complex searches, but I don't see any limitations mentioned for FVH.
The documentation indicates the plain highlighter can suffer from poor performance under certain situations and was hoping to use FVH instead, though I have no real-world benchmarks as we're only in the proof-of-concept stage.
