How Are Search Engines So Fast?

The video discusses the frustration of searching for files on a computer compared to the speed of Google's search engine. It explains that Google's speed is due to its algorithm and indexing, which pre-crawls the web to create an index, allowing for quick retrieval of search results. In contrast, home computers often lack such indexing, leading to slower searches. The video concludes with a call to support SciShow on Patreon.
