Google Search

What it is

Google Search is the world's most widely used web search engine. It uses sophisticated crawling, indexing, and ranking algorithms (including AI models like RankBrain and Gemini) to organize the world's information.

What problem it solves

It provides near-instant access to billions of web pages, allowing users to find specific facts, resources, or services across the global internet.

Where it fits in the stack

AI & Knowledge. It is often used as a "grounding" source for AI agents via search APIs (Google Custom Search API) or as a baseline for AI-powered search tools like Perplexity.

Typical use cases

  • Finding specific documentation or technical resources.
  • Verifying facts or current events.
  • Providing real-time web context to LLMs via "Search Tool" integrations.

Strengths

  • Unrivaled Index Size: Finds niche content that other search engines might miss.
  • Speed: Extremely fast response times.
  • Integration: Deeply connected with the broader Google ecosystem (Maps, News, Books).

Limitations

  • SEO Pollution: Search results are often dominated by ad-heavy or AI-generated "content farms."
  • Privacy: Tracking and profiling of search history is central to the business model.
  • Information Bubbles: Personalized results can restrict exposure to diverse perspectives.

When to use it

  • For general information retrieval.
  • When you need to find a specific website or authoritative source.

When not to use it

  • For highly private or sensitive queries (consider SearXNG).
  • When you need deep, synthesized research answers with citations (consider Perplexity).
