🚀 How Search Engines Actually Work | Crawling, Indexing & Ranking

This is the recording of the live Discensys session conducted on 23 May 2026, where we explored how modern search engines actually work internally — from web crawling and indexing to ranking algorithms and search result retrieval. The session covers how search engines discover web pages, organize massive amounts of information efficiently, and rank results based on relevance, authority, and user intent. We also discussed the underlying systems that enable fast and scalable search across billions of web pages. Discensys is a community-driven open learning initiative focused on making structured, high-quality learning accessible through free weekend sessions. Topics covered: • How web crawling works • Search engine indexing systems • Ranking algorithms and relevance scoring • Query processing and retrieval pipelines • Distributed search infrastructure • Real-world examples from modern search engines 📂 Slides & resources: Link available in the comments #searchengines #systemdesign #backenddevelopment #softwareengineering #computerscience
