Chapter 8: Search Engines

How Do Search Engines Work?


Please note: search engines are not simple. They include incredibly detailed processes and methodologies, and are updated all the time. This is a bare bones look at how search engines work to retrieve your search results. All search engines go by this basic process when conducting search processes, but because there are differences in search engines, there are bound to be different results depending on which engine you use.
  1. The searcher types a query into a search engine.
  2. Search engine software quickly sorts through literally millions of pages in its database to find matches to this query.
  3. The search engine's results are ranked in order of relevancy.
