I want to return the first n characters of the field if nothing returns from the highlight query - this should technically be covered by the no_match_size functionality, but it doesn't seem to be working.
no_match_size
The amount of text you want to return from the beginning of the field if there are no matching fragments to highlight. Defaults to 0 (nothing is returned).

My problem is exactly like a previous post here that was never answered: Highlighter doesn't work with custom _all field and no_match_size.
Does anyone know how to get this working, have any insights, or confirmation that this is a bug? Thanks!
