Package dev.langchain4j.rag.query.router

Interface QueryRouter

  • All Implemented Interfaces:
    
public interface QueryRouter

    Routes the given Query to one or multiple ContentRetrievers. The goal is to ensure that Content is retrieved only from relevant data sources. Some potential approaches include: 

    - Using an LLM (see LanguageModelQueryRouter)
- Using an EmbeddingModel (aka "semantic routing", see 
    EmbeddingModelTextClassifier
     in the 
    langchain4j
     module)
- Using keyword-based routing
- Route depending on the user (
    query.metadata().chatMemoryId()
    ) and/or permissions
