重新排序器 Cohere(Reranker Cohere)#
Reranker Cohere 节点允许你对来自向量存储的结果块进行重新排序。你可以将此节点连接到向量存储。
🌐 The Reranker Cohere node allows you to rerank the resulting chunks from a vector store. You can connect this node to a vector store.
重排序器会根据给定查询，按相关性降序排列从向量存储中检索到的文档列表。
🌐 The reranker reorders the list of documents retrieved from a vector store for a given query in order of descending relevance.

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.
