A prompt can rebuild

A minimalist search engine homepage with a logo, search bar, and buttons. Sophisticated JavaScript handles form submission, performance monitoring, analytics, and error tracking.

What you can't see

Massive distributed backend: search indexing (billions of documents), ranking algorithms, real-time query processing, distributed databases, caching layers, personalization engine, spam detection, ML models for suggestions, observability/logging infrastructure, geographic distribution across data centers.
