Andrey Kudryavtsev updated SOLR-5388: ------------------------------------- Description: Ability for expressions like _def(min(field1,..,fieldN), defValue)_ return _defValue_ if document doesn't have value for any of this fields. Implement _exists(int doc)_ method for FunctionValues created in MultiFloatFunction. Extract method to get ability other MultiFloatFunction implementation to override it. Example: Doc1: Field1: "10", Field2: "20" Doc2: Field3: "30", FIeld4: "40" We want to call user function "def(min(Field1,Field2),5)" for this documents : Now we've got: Doc1 = 1, Doc2 = Float.POSITIVE_INFINITY With this patch: Doc1 = 10, Doc2 = 5 ( Doc2 doesn't have values for this documents, so he gets defValue) was: Ability for expressions like _def(min(field1,..,fieldN), defValue)_ return _defValue_ if document doesn't have value for any of this fields.
