Module cross_encoder 

Cross-encoder reranking implementation Cross-Encoder reranking for improved retrieval accuracy

Cross-encoders jointly encode query and document, providing more accurate relevance scores than bi-encoder approaches. This implementation provides a trait-based interface that can be backed by ONNX models, API calls, or other implementations.
