I cannot check equality against null in Solr 9.0. It always raise exception. IE:
having( STREAM eq(any_valid_field, null)) "EXCEPTION": "Unable to check eq(...) because a null value was found" Does the statement below changed in Solr 9.0? Thanks! if Syntax <https://solr.apache.org/guide/8_4/stream-evaluator-reference.html#if-syntax> The expressions below show the various ways in which you can use the if evaluator. if(fieldA,fieldB,fieldC) // if fieldA is true then fieldB else fieldC if(gt(fieldA,5), fieldA, 5) // if fieldA > 5 then fieldA else 5 if(eq(fieldB,null), null, div(fieldA,fieldB)) // if fieldB is null then null else fieldA / fieldB
