Use Cases

• Search-as-you-type UI: Real-time autocomplete dropdown. Debounce 150-300ms.
• Query refinement for RAG: Expand partial/ambiguous queries before calling web-search or llm-context.
• Entity detection: Use rich=true to detect entities with title, description, and image for preview cards.
• Typo-tolerant input: Get clean suggestions from misspelled input without separate spellcheck.

Notes

• Latency: Designed for <100ms response times
• Country/lang: Hints for suggestion relevance, not strict filters
• Typo handling: Suggestions handle common typos without separate spellcheck
