RAG Query Transformation Skill

Capabilities

  • •Implement query expansion techniques
  • •Configure Hypothetical Document Embeddings (HyDE)
  • •Set up multi-query generation
  • •Design query decomposition strategies
  • •Implement step-back prompting
  • •Configure query routing for specialized indices

Target Processes

  • •advanced-rag-patterns
  • •knowledge-base-qa

Implementation Details

Transformation Techniques

  1. •Multi-Query Generation: Generate query variations
  2. •HyDE: Generate hypothetical answer, embed that
  3. •Query Decomposition: Break complex queries into sub-queries
  4. •Step-Back Prompting: Generate higher-level queries
  5. •Query Expansion: Add synonyms and related terms

Configuration Options

  • •Number of query variations
  • •LLM for query generation
  • •Decomposition depth
  • •Query routing rules
  • •Result fusion strategy

Best Practices

  • •Match technique to query complexity
  • •Test with representative queries
  • •Monitor retrieval quality changes
  • •Balance latency vs quality tradeoffs

Dependencies

  • •langchain
  • •LLM provider
