Hi,
I am using Solr 8.5.2 with the LTR feature enabled. I have successfully
uploaded a trained model to Solr. When I add rq={!ltr model=model
efi.query=$q reRankDocs=100} param to my regular search query, it works.
But when I pass a shards param with a list of shards then I run into the
following error. Any ideas why this might be the case?
