HI Everyone I am using vector search in Solr 9.4. I am using cosine similarity with knn parser.
Same as the documentation https://solr.apache.org/guide/solr/latest/query-guide/dense-vector-search.html Schema <fieldType name="knn_vector" class="solr.DenseVectorField" vectorDimension="768" similarityFunction="cosine"/> <field name="vector" type="knn_vector" indexed="true" stored="true"/> Query q={!knn f=vector topK=10}[1.0, 2.0, 3.0, 4.0] The problem is it always returns docs even if it's not relevant. Even if I am using the xyz keyword, knn parser is returning the documents which is useless. I want to control the similarity of documents. I need highly similar documents only. Does Solr have any parameter in the knn parser which controls the similarity threshold ? *How can I control the minimum Similarity threshold with knn parser ?* Please help. Thanks in advance. -- Thanks & Regards Kumar Gaurav
