"Did you mean?" UI: Show users a corrected suggestion before running the search
Batch query normalization: Clean up user inputs in bulk

Built-in alternative: Web Search and LLM Context have spellcheck=true by 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
