You are implementing Retrieval-Augmented Generation (RAG) using Azure AI Search and Azure OpenAI. Users report that when searching for technical product specifications, the system occasionally retrieves outdated product manuals because newer versions share similar titles. What configuration change should you make to improve retrieval accuracy?
Trap 1: Increase the chunk size parameter in the document ingestion…
Larger chunks do not resolve version ambiguity; they dilute the embedding with more unrelated text, worsening discrimination between similar titles. Chunk size tuning suits improving context completeness for long documents, not separating near-identical manual versions.
Trap 2: Decrease the temperature parameter of the Azure OpenAI generation…
Temperature controls randomness in generated text, not which documents Azure AI Search returns, so retrieval of outdated manuals is unaffected. Setting temperature to 0.0 is correct when the requirement is deterministic, factual generation rather than retrieval ranking.
Trap 3: Switch the embedding model from text-embedding-ada-002 to…
Swapping embedding models changes vector dimensionality and semantic quality but does not encode document recency, so newer and older manuals still rank similarly. Model upgrades suit general semantic accuracy gains, not filtering by version or date.
- A
Increase the chunk size parameter in the document ingestion pipeline to 4000 tokens
Why it fails: Larger chunks do not resolve version ambiguity; they dilute the embedding with more unrelated text, worsening discrimination between similar titles. Chunk size tuning suits improving context completeness for long documents, not separating near-identical manual versions.
- B
Decrease the temperature parameter of the Azure OpenAI generation model to 0.0
Why it fails: Temperature controls randomness in generated text, not which documents Azure AI Search returns, so retrieval of outdated manuals is unaffected. Setting temperature to 0.0 is correct when the requirement is deterministic, factual generation rather than retrieval ranking.
- C
Switch the embedding model from text-embedding-ada-002 to text-embedding-3-small
Why it fails: Swapping embedding models changes vector dimensionality and semantic quality but does not encode document recency, so newer and older manuals still rank similarly. Model upgrades suit general semantic accuracy gains, not filtering by version or date.
- D
Enable semantic search and semantic ranking on the Azure AI Search index
Semantic search and semantic ranking re-rank results using language understanding rather than keyword overlap alone, so a newer manual whose title closely matches an older one is promoted above the outdated version, improving retrieval accuracy for technical specifications.
