How is Google able to search so quickly and accurately given the huge amounts of data on the web?
user
Here is a list of reasons why Google is able to search huge amounts of data so quickly and accurately:
1. Google keeps and updates a local copy of the web to avoid downloading web pages on every query. 
2. Googles copy of the web is pre-processed and stored in a form that makes querying efficient, e.g. Google builds an index of all websites, much like the index in a book, to do efficient keyword lookups.
3. Google has data centers spread throughout the world that have huge bandwidth and that allows for parallel processing of search queries.
4. Google's code is heavily optimized and uses general performance techniques like caching, where common search results are save in memory, and thus can be returned almost instantly.
