5. HOW DO SEARCH ENGINES WORK?
 Spider “crawls” the web to find new documents (web pages, other documents)
typically by following hyperlinks from websites already in their database
 Indexing Once the spiders have completed the task of finding information on
Web pages, the search engine must store the information in a way that makes
it useful.
 Search engines indexes the content (text, code) in these documents by adding
it to their databases and then periodically updates this content
 Search engines search their own databases when a user enters in a search to
find related documents (not searching web pages in real-time)
 Search engines rank the resulting documents using an algorithm
(mathematical formula) by assigning various weights and ranking factors
 Page Rank is a family of algorithms for assigning numerical weightings to
hyperlinked documents (or web pages) indexed by a search engine.
