Honestly, I'm not exactly sure about that myself. Someone asked for that feature on reddit and I realized that it wouldn't be too hard to add it, so I did. Another poster here mentioned that it might be useful for doing word-level highlighting of what was most relevant to a semantic query string within a sentence. I do think it is able to capture a lot more nuance simply because it's giving you so much more data. The question is how best to leverage that incremental data and take advantage of it, and I'm still trying to figure that out.
