Reranking with Cohere ✅

When retrieving documents for RAG, initial vector similarity search may miss important semantic matches.

Cohere’s reranking service helps improve result relevance by reordering documents using multiple scoring factors.

import { rerank } from "@kastrax/rag";
 
const results = rerank(
  searchResults,
  "deployment configuration",
  cohere("rerank-v3.5"),
  {
    topK: 5,
    weights: {
      semantic: 0.4,
      vector: 0.4,
      position: 0.2
    }
  }
);
