Spider “crawls” the web to find new documents (web pages, other documents) typically by following hyperlinks from websites already in the database
Search engine indexes the content (text, code) in these documents by adding it to their huge databases and periodically updates this content
Search engine searches its own database when user enters in a search to find related documents (not searching web pages in real-time)
Search engine ranks resulting documents using an algorithm (mathematical formula) that assigns various weights to various ranking factors
