# Rerank

Rerank orders candidate content by relevance to a query. Use a reranking-capable model visible to the current credential, submit the query and candidate list in the Rerank request format, then read the ordered results from `results[]`.

Keep candidate identifiers in the application so that a returned rank can be mapped back to the original content. Test the selected model and input type with a small request before using Rerank in a production retrieval flow.
