I am a bit puzzled by the output of ts_headline (V8.3) for different queries.
It seems that the difference is in the number of occurrences of the criterion
words. If the number of hits is less than some number, the ts_headline result
is "correct" but if the number of hits exceeds that limit, the result is just
the first MinWords of the "document".
I have seen cases with up to 20 hits succeed but cases with 35 hits miss.
The spread of hits does not seem to be relevant.

Are you bumping into the MaxWords limit? If you've got 35 hits that must
be at least 35 words.
