Cross-encoders score a query and a document in one pass, which makes them more accurate than embedding search and too slow for a whole corpus. Use them to rerank the top hits.

Retrieval-augmented generation is an architecture, and the vector database is one box in it. The whole loop, the RAG variants worth knowing, reranking, and when a knowledge graph beats similarity.

cross-encode-rs: Rust ONNX cross-encoder reranking (Qdrant blog)

Qdrant’s Clelia Bertelli blog (Sep 25, 2026) covers cross-encode-rs—a Rust ONNX Runtime cross-encoder for reranking. crates.io owner is AstraBert (not a Qdrant-org crate). ~1.1×/~1.4× vs Python stacks on M4 Max are vendor-reported; all three hand work to onnxruntime. Linux/macOS only.
