Tips
- Web: Use
type: "fast"for quick lookup,"deep"for thorough research - Code: Lower
tokensNum(1000-2000) for focused, higher (5000+) for comprehensive - See examples.md for more patterns
Fallback
If all the above are not suitable for users' question or the tool failed, fallback to Multi Search Engine (multi-search-engine) tool
