¥Contextual Compression Retriever node

上下文压缩检索器节点通过考虑查询中的上下文来改进矢量商店文档相似性搜索返回的结果。

¥The Contextual Compression Retriever node improves the answers returned from vector store document similarity searches by taking into account the context from the query.

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.
