no John G. there is a reference that QA evaluator takes for evaluation that is "reference denotes the content of each document, and document_position denotes the (zero-based) index in each span's list of retrieved documents." but in my case I am not using a document as reference I want to verify my QA correctness wrt SQL DB so instead of document I provide for reference, is there any way I can provide my SQL DB as refernce for validating my Input and output response
