Hi there! I have the following use case I'd like to implement in Solr and hence are seeking for information onto the internals of Solr and the performance of such an approach.
I would like to score documents matched by a query using a custom scoring function. Generally, up to my knowledge, there are two options to achieve this: 1) implement a custom ValueSource and use it via a FunctionQuery 2) implement a CustomScoreQuery and its customScoreProvider function that would return a CustomScoreProvider instance that would be used for custom scoring. The custom scoring function is expected to score based on a reference value and a value of a binary doc-values field. How are FunctionQueries in contrary to a CustomScoreQuery executed? What approach would in your opinion yield better performance, and why? Thanks, Dominik
