Compute LSR scores for a specific query and document using compute_query_document_score

[littlewine]

Hi all,

Is it possible to compute individual query-document scores for LSR methods, eg using the IndexReader.compute_query_document_score method or some other way?
When doing retrieval with Anserini, I see that according to the instructions, I have to use --impact and --pretokenized, but the IndexReader and its method seem to accept very limited parametrization/arguments (in fact I couldn't even change the default BM25 weights, at least without modifying the framework itself).

Am I missing something here?
What would be the best way to achieve this?

Hi @littlewine - you're absolutely right... compute_query_document_score is currently hard-coded to BM25 with limited parameterization... but we just need to expose the right hooks... PRs welcome!
