Hello, Just noticed my numbering is off, should be:
1. Deploy a feature store from a JSON file to each collection. 2. Reload all collections as advised in the documentation: https://lucene.apache.org/solr/guide/7_5/learning-to-rank.html#applying-changes 3. Deploy the related model from a JSON file. 4. Reload all collections again. An update: applying this process twice I was able to fix the issue. However, it required "patching" individual collections, while reloading was done for all collections at once. I'm not sure this is very transparent to the user: maybe show the model deployment status per collection in the admin UI?
