# Does it support caching, real-time data, and AI Overview?

The Google Search parameter docs state that identical searches are cached for **5 minutes** by default, and cached searches are free and not counted in search statistics. Use `no_cache=true` for fresh results. The docs also support `ai_overview=true`; a successful AI Overview fetch usually costs **1 response**, but may cost **2 responses** if a second request is needed for `page_token`.
