# Reranker Cohere

The Reranker Cohere node allows you to [rerank](../../../../../glossary/#ai-reranking) the resulting chunks from a [vector store](../../../../../glossary/#ai-vector-store). You can connect this node to a vector store.

The reranker reorders the list of documents retrieved from a vector store for a given query in order of descending relevance.

On this page, you'll find the node parameters for the Reranker Cohere node, and links to more resources.

Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five `name` values, the expression `{{ $json.name }}` resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five `name` values, the expression `{{ $json.name }}` always resolves to the first name.
