The post asks if there are any examples of using the Contextual Compression Retriever with LLamaIndex, and provides a link to the relevant documentation. The comments suggest that the Contextual Compression Retriever may be similar to the optimizer in LLamaIndex, and that the Langchain's method could potentially be implemented as a custom retriever in LLamaIndex. However, there is no explicitly marked answer in the provided information.
