Chapter eleven:

Using the Internet

A. Boolean Logic
B. Noodle Tools
C. Find Articles

A. Finding facts and information with search engines to support your arguments about your topic or for rebuttals about your topic can be aided by using Boolean logic with the search engine.

B.The Noodle Tools - Information Literacy: Search Strategies

C. Finding Articles

Draft I is due Sept 16th and your Final paper is due Sept 30th.
In order to better understand both sides of the argument for your topic use the Boolean operators to search other web sites that may also have relevant information about your subject as well as Noodle Tools.
Combine this information to refine the rough Draft I as well as giving you more to think about for the final arguments in your Final paper.

Web sites to help you find information

Assignment 2.:

1. Use the Noodle Tools to find more information about your subject.

2. Use the Boolean operators discussed below and use them in the Google Search Engine above.

3. Use Find Articles web site

Boolean Searching: An Introduction

Internet search engines provide access to huge amounts of information. So much information that in order to find what you're looking for, you need to know how to use Boolean operators - British mathematician George Boole's contribution to information retrieval.
Boolean searching is a set of rules and operators which allow you to define exactly how you want your search done.

Logical Operators

Boolean searching uses three logical operators:

Quotation Marks

Some search engines will let you use quotation marks. Quotation marks tell the computer that you are looking for a phrase or group of words exactly as you type it. So,

"naval warfare"will only find results where the words "naval" and "warfare" are right next to each other.


Parenthesis "force" a search engine to do a search in certain order. So,
(naval OR ship OR boat) NOT warfare

will make the search engine sort through the results of "naval OR ship OR boat" first, then delete all the ones that have "warfare."


The best way to use Boolean searching is to combine as many logical operators as possible to try to narrow the search. If this doesn't give enough results, then start taking terms off. Try to think of words that mean the same thing, and things you don't want in your search. Otherwise, a simple search can give hundreds - or thousands - of resultsÉ and that's next to useless.

Using Boolean Logic in Searches

Boolean logic is a very simple, yet powerful programming language.   It consists of the simple keywords: AND, OR, and NOT.   These three logic keywords can greatly increase the accuracy of your keyword searches on most search engines. 

Be forewarned that different search engines may use different Boolean symbols.  Some engines may even use the name instead of the symbol.  Most search engines use the plus (+) and minus (-) signs when reading search criteria. Read the help files if in doubt.

Name Symbol



Most search engines default to AND.  Use AND when you want all the keywords to appear in the results. +Banana +Bread
&Banana & Bread   

Returns all pages that mention banana and bread, but not in any specific order
OR | Used when you want either word to appear in the search results.  The pipe symbol is above your enter key. Banana | Bread

Returns all pages that mention either banana or bread.   Pages with both words mentioned will rank higher
Used when you want exclude words from a search Banana &! Bread
+Banana -Bread

Returns pages that mention Bananas, and not any pages that also contain Bread.
Wildcard * Used to match partial words.  Use wildcards at the end portion of a word comput*

Returns pages that mention compute, computer, computation, etc.
Quotation Marks "   " Used to enclose phrases.  Search results will contain complete phrase "Great wall of China"

Returns pages that mention the complete text: Great wall of China 
Parenthesis (  ) Used to create complex Boolean searches.  Remember your order of precedence from algebra? 

e.g: ((6*2)+4)=16  (6*(2+4)) = 36

*note:  If you do not get the desired results you should read the search engines help files as the search engine may read from right to left rather than from left to right..

(((Banana | strawberry)
daiquiri) +(cake OR "ice cream"))

Returns pages mentioning (((Banana or Strawberry) not  daiquiris) and cake or ice cream))
