OK so to restate, you expect the sort specified to be applied to both the
“outer” and “inner” queries. Makes sense, seems like a good enhancement.
Hmm, I wonder if you can put the sort parameter in with the rerank
specification, like: q={!rerank reRankQuery=$rqq reRankDocs=1200 reRankWeight=3
sort="score desc, downloads desc”}
That doesn’t address your initial point, just curious if it’d do as a
workaround meanwhile.
Best,
Erick
