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.


Boolean operator quotation marks

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.
