-------------------------------------------
Summary: Add efSearch parameter to knn query
Key: SOLR-17928
URL: https://issues.apache.org/jira/browse/SOLR-17928
Project: Solr
Issue Type: Improvement
Components: vector-search
Reporter: Ishan Chattopadhyaya
Right now, only topK can be requested. efSearch is a standard overfetch
parameter.
Proposing that we add it for better recall accuracy.
(FYI, Elasticsearch calls it num_candidates. Commonly referred to as efSearch,
similar to efConstruction that we call beamWidth)
