Using Boolean Operatorsand other Internet Search Tools

AND, OR, NOT, Parenthesis, Quotation Marks, Plus and Minus Signs

let s get started
Let’s Get Started
  • Searching the internet can be a daunting task.
  • You could spend hours on an unfocused quest.
  • The internet can be organized into sensible information by using search tools.
boolean operator and
-Boolean Operator-AND
  • If you enter AND between two words then your search will only yield documents that contain both words, narrowing your search.
  • If you enter rage and traffic then your search will yield only documents with both words.
boolean operator or
-Boolean Operator-OR
  • If you enter OR between two words then your search will look for either word (you don’t care which word), broadening your search.
  • If you type in rage OR anger in your search engine then your search will yield documents that contain the word rage or the word anger.
boolean operator not
-Boolean Operator-NOT
  • Not tells the search engine to disregard those documents that contain a word.
  • This is a powerful command and should be used sparingly.
why not not
Why not NOT?
  • If you search goldfish and guppy and get lots of information about swordtails, you might be tempted to try NOT swordtails.
  • But what if the best authority on goldfish is an authority on swordtails, too? What if her name is Ira Swordtail? You could miss lots of information.
boolean operator parenthesis
-Boolean Operator-Parenthesis ( )
  • Search engines do not read left to right.
  • Most interpret the AND first, then follow with the OR.
  • You can tell the search engine to interpret the OR first by typing (Rage OR Anger) AND traffic.
  • Don’t use ( ) when you’re only using AND.

now give it a try
Now Give it a Try
  • Each search engine has different rules about upper and lower case letters and the use of Boolean operators. Check their directions.
  • Try some experimental searches. Browse the results and make any necessary adjustments to the structure of your search words and operators.
  • With a little practice, you can save hours of time in cyberspace and focus on the task at hand.
