Query Transformation Techniques
Explore methods to rephrase or expand user queries for more effective retrieval from the vector database.
What's Query Transformation?
In Retrieval Augmented Generation (RAG), the quality of the information retrieved from your vector database directly impacts the LLM's response. Sometimes, the raw user query isn't ideal for retrieval.
Query transformation is the process of modifying a user's original query to make it more effective for searching your vector database.
Why Original Queries Fall Short
User queries can be:
- Too short or vague: Lacking enough detail for precise retrieval.
- Ambiguous: Open to multiple interpretations.
- Colloquial: Using informal language that doesn't match document embeddings.
- Complex: Asking multiple questions at once.
These issues lead to irrelevant context being retrieved, impacting RAG quality.
