German Martin	736a1819aa	LOTR: Lord of the Retrievers. A retriever that merge several retrievers together applying document_formatters to them. (#5798) ... "One Retriever to merge them all, One Retriever to expose them, One Retriever to bring them all and in and process them with Document formatters." Hi @dev2049! Here bothering people again! I'm using this simple idea to deal with merging the output of several retrievers into one. I'm aware of DocumentCompressorPipeline and ContextualCompressionRetriever but I don't think they allow us to do something like this. Also I was getting in trouble to get the pipeline working too. Please correct me if i'm wrong. This allow to do some sort of "retrieval" preprocessing and then using the retrieval with the curated results anywhere you could use a retriever. My use case is to generate diff indexes with diff embeddings and sources for a more colorful results then filtering them with one or many document formatters. I saw some people looking for something like this, here: https://github.com/hwchase17/langchain/issues/3991 and something similar here: https://github.com/hwchase17/langchain/issues/5555 This is just a proposal I know I'm missing tests , etc. If you think this is a worth it idea I can work on tests and anything you want to change. Let me know! --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago
