Search Strategies
Engine versus Directory
Who is on top?Boolean operationsSpecial Commands
What’s the difference?
SEARCH ENGINE DIRECTORY
http://www.learnthenet.com/animated-internet/how-search-engines-work/index.php
Examples
SEARCH ENGINE DIRECTORY
Search strategies
How they work (or which site goes first?)
There are equations,
(but not this one!)
The factors include:
Paid (sponsored- at the top)Search term is the urlSearch term is in the titleBased on # links to the site
(different for each service)
For our students:
The first link might not be the best!
Search strategies
Boolean OperatorsIt is all in 3 little words-
and, or , not
And ( or the +)
Or ( you get everything)
Default setting for most engines
Not ( or the -)
