Hi, I'm trying to write a custom DoubleValuesSource for use with a FunctionScoreQuery instance.
To generate the final score of a document I need to: 1) Read from three indexed docValue fields and 2) Use the score of the wrapped query passed in to the FunctionScoreQuery instance For example, a document A would be scored using a formula like: ((docA's_score_from_wrapped_query * some_value_x) + (docA's_field1_value * some_value_y) + (docA's_field2_value * some_value_z)) * docA's_field3_value How do I accomplish this? Can this be done using one custom DoubleValuesSource or do I need one for reading from each of the indexed docValue fields and then use a combination of MultiFloatFunctions and SumFloatFunctions to achieve this? Appreciate your time and help. Thanks, Kevin
