NBoost is a scalable, search-api-boosting platform for deploying transformer models to improve the relevance of search results on different platforms (i.e. Elasticsearch)
There's no specific ES version for nboost. However, if there are differing request/response formats you may have to configure the paths (--topk_path, --query_path, etc).
I intent to deploy nboost on AWS ES service, but AWS ES service only support ES v7.1, is there a dependency on which ES version for nboost?
