Retrieves semantically similar documents for multi-turn conversation scenarios by processing message inputs that include conversation history. By deeply parsing context information, this operation ensures that the retrieval results are highly relevant to the current conversation and provides consistent and efficient information retrieval services for complex interactive environments.
