+# Cohere Rerank
+
+Reranking documents can greatly improve any RAG application and document retrieval system.
+
+At a high level, a rerank API is a language model which analyzes documents and reorders them based on their relevance to a given query.
+
+Cohere offers an API for reranking documents. In this example we'll show you how to use it.
+
+## Setup
+
+import IntegrationInstallTooltip from "@mdx_components/integration_install_tooltip.mdx";
+
+<IntegrationInstallTooltip></IntegrationInstallTooltip>
+
+```bash npm2yarn
+npm install @langchain/cohere
+```
+
+import CodeBlock from "@theme/CodeBlock";
+
+import Example from "@examples/document_compressors/cohere_rerank.ts";
+
+<CodeBlock language="typescript">{Example}</CodeBlock>
+
+Here, we can see the `.rerank()` method returns just the index of the documents (matching the indexes of the input documents) and their relevancy scores.
+
+If we'd like to have the documents returned from the method itself, we can use the `.compressDocuments()` method.
+
+import ExampleCompressor from "@examples/document_compressors/cohere_rerank_compressor.ts";
+
+<CodeBlock language="typescript">{ExampleCompressor}</CodeBlock>
+
+From the results, we can see it returned the top 3 documents, and assigned a `relevanceScore` to each.
+
+As expected, the document with the highest `relevanceScore` is the one that references Washington, D.C., with a score of `98.7%`!
