Identifying Best Match Field in Document Search

TLDR Jack wanted to display the best match field in a document search. Despite Kishore Nallan's suggestion of looking at field weights, Jack decided to sort highlighted fields by number of matched tokens.

Is there a way to tell which field in a document was the "best" one when performing a search? I see a best_field_score field, but I can't see one telling me which field was the best?

There's also a best field weight which might help identify the field. But weights are normalised so might not match exactly with values sent if the weight values are large.

Ofc if several fields share weights then this won't help.

I'm not sending any specific weights right now, so I assume all of the fields are weighted the same.

Essentially I want to show only the field that "most" matched the search term in the UI - is there another way to go about doing that?

Hmm that's not quite possible

I guess I'll just sort the highlight fields by number of matched tokens and pick the highest one then, cheers.
