The community member is trying to evaluate a retriever with a node postprocessor using the LlamaIndex evaluator, but they are unsure where to put the reranker since the evaluator only accepts retrievers, not node postprocessors. The community members suggest that the community member could create their own custom retriever, and provide a link to the LlamaIndex documentation on how to define a custom retriever.
i wanna eval retriever with node postprocessor using llamaindex evaluator, but I don't know where to put the reranker since the evaluator only accept retriever not node postprocessor, is there a retriever bundled with node postprocessor ?
