 | the Boolean operator NOT |
 Here
we go, Wendi. Your last lesson on Boolean operators. |
|
 YES!
I mean, done so soon, Will? |
|
 Very
funny! Remember how the Boolean operator AND narrowed your search by
giving you only pages that contained both of your keywords?
|
|
 Yeah,
yeah, go on. |
|
| The
Boolean operator OR broadened your search by giving you web pages that
contained your first keyword, pages that contained your second keyword,
and pages that contained both keywords.
|
|
| I
remember already! |
|
| Well,
I'm going to teach you about one more operator--NOT. |
|
| Wonderful. |
|
| NOT
helps you narrow your search by eliminating pages containing your second
keyword. |
|
| So
if I wanted to buy a jazz CD but didn't want to find info on the Utah
Jazz basketball team, I would type Jazz NOT
Utah or Jazz NOT basketball.
Right? |
|
| You're
getting good at this, Wendi. Just remember that some search engines
require you to use AND NOT. Yet
others use a - (minus sign); for example: jazz
-Utah. |
|
| OK,
show me the Venn diagram.
|
|
 Jazz
NOT Utah will give you only pages with the word Jazz. Pages with the
word Utah (like Utah Jazz) will be eliminated. The yellow part of the
diagram shows your results.

|
| Congratulations,
Wendi! All you have to do is take another quiz and complete Activity #4 in your packet, and
you're home free. |
|
| Home? No way. I'm going to the mall! Move it, Will!
