AI-103 Implement Generative AI And Agentic Solutions Practice Question
You are developing a RAG solution using Azure AI Search. Users are searching using domain-specific acronyms that are not well-represented in standard embedding models, resulting in poor retrieval scores. What feature should you enable in Azure AI Search to improve keyword matching for exact acronyms?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Hybrid search combining vector search and full-text BM25 search
Hybrid search combines vector search (for semantic meaning) with full-text keyword search (BM25 algorithm), ensuring exact acronyms and part numbers are matched reliably.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increasing the embedding dimension size to 3072
Why it's wrong here
Larger embedding vectors still struggle with rare acronyms unless keyword matching is utilized.
- ✗
Enabling Azure AI Content Safety filters
Why it's wrong here
Content Safety filters moderate harmful content, not search ranking algorithms.
- ✗
Setting the semantic ranker threshold to zero
Why it's wrong here
Threshold adjustments filter results but do not improve underlying keyword recall.
- ✓
Hybrid search combining vector search and full-text BM25 search
Why this is correct
Hybrid search merges vector embeddings with keyword BM25 scoring, capturing both semantic intent and exact keyword matches like acronyms.
