I wonder if it'd be possible to handle this all at the shard level. If the request is really constant-score, then in principle it should be possible to populate `maxScore` (and pseudo-`score` fields) by scoring just a single doc. This would address the backcompat concerns that @gus-asf raised. I came around to this thought because `rows=0` isn't the only case that it makes sense to optimize here. As David suggests, "explicitly set "fl" to something that does not include score" is indeed a workaround for the `rows=0` case -- but for sort by score alone (and MatchAllDocs or constant-score query) `rows > 0` can also skip sort and score evaluation (simply returning a DocList in index order), which would be _way_ faster than any "workaround" sort, for the `rows > 0` case. -- This is an automated message from the Apache Git Service.
