Using Boolean Operators

1
Using Boolean Operators

• AND, OR, NOT

2
Let get started!

• Searching the NET can be a daunting task.
• You could spend hours on an unfocused quest.
• The NET can be organized into sensible
  information by using search tools.

3
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 goldfish AND guppies then your
  search will yield only documents with both words.

4
Boolean Operator OR

• If you enter OR between two words then your
  search will look for either word (you dont care
  which word), broadening your search.
• If you type in goldfish OR guppies in your
  search engine then your search will yield
  documents that contain the word goldfish or the
  word guppies.

5
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?
If you search goldfish and guppy and gets 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 Irma
Swordtail? You could miss lots of information.
