Use Cases
- Pre-search query cleanup: Check spelling before deciding which search endpoint to call
- "Did you mean?" UI: Show users a corrected suggestion before running the search
- Batch query normalization: Clean up user inputs in bulk
Notes
- Built-in alternative: Web Search and LLM Context have
spellcheck=trueby default — use this standalone endpoint only when you need the correction before searching - Context-aware: Corrections consider the full query context, not just individual words
