1. A search application needs to return results for both exact keyword matches (e.g., a specific part number) and conceptually related queries (e.g., "failure" matching content about "malfunction") in the same query. Which search approach BEST satisfies both needs?
- A. Pure keyword search only, since exact matching is sufficient for all use cases
- B. Pure vector search only, since semantic similarity always outperforms keyword matching
- C. Hybrid search combining keyword (lexical) search and vector (semantic) search✓ Correct
- D. Enrichment skills alone, with no search index involved
Explanation
Hybrid search combines lexical/keyword matching (precise for exact terms like part numbers) with vector/semantic search (captures conceptual similarity like "failure" and "malfunction"), satisfying both requirements in a single query. Option A would miss the semantic/conceptual matches entirely. Option B risks missing exact-match precision that keyword search reliably provides for specific identifiers like part numbers. Option D describes a content-processing step, not a query-time search capability, and does not itself return ranked results.
