    • Truncation/wildcards
  • Watch Video Tutorials from ENGL 101 

Evaluation

Evaluating your sources is the most important thing you can do.

The criteria to evaluate sources include:

  • Accuracy
  • Authority
  • Objectivity
  • Currency
  • Coverage

These criteria are considered more in-depth in the file below.

Research Process

Just like the writing process, research has a process that should be followed when finding information. The steps of the research process are in the files below.

Introduction to Search Techniques

Searches of computerized resources are more effective if you know how to "talk to" the computer systems. Communicating with these systems requires knowing certain basic search techniques.

Because these techniques are so important for getting good search results, you should take the time to understand them and practice using them. They will vastly improve your search results in information services and when searching the Internet.

Whenever you begin to use a new computerized resource, look for "help" (or "search tips" or "instructions") that will tell you which of these search techniques is available in the resource and how to apply them in the specific resource you are using. As you read through these techniques, try them out by conducting your own searches in a search engine or database. 

The search techniques introduced on this webpage are: Boolean operators, phrase searching, truncation/wildcard, and nesting. 

Boolean Operators (Connector Words)

Connectors or operators are used to tell the computer how to combine the words you want to search. The Boolean operators "AND", "OR", and "NOT" are described below.  Note: Some research databases require that the Boolean operator be capitalized: AND, OR, NOT

AND

Use the connector "and" to tell the system that both terms are needed to describe the subject. That is, both terms must occur in the description of the article. For example, to search the topic "censorship of music" connect the keywords with "and" by typing:

censorship AND music

Both the word "censorship" and the word "music" will be in the items found.

Additional examples:

firearms AND legislation
divorce AND statistics AND dakota

 

OR

Use the connector "or" to tell the system that either one word or the other must appear in the description of the item. (This connector is used where alternative words may be used to describe the same subject). For example, if you type:

bones OR skeleton

Either the word "bones" or the word "skeleton" will be in the items found.

Additional examples:

mice OR mouse
farms OR ranches

 

NOT

Use the connector "not" to find items that have one word and do not have the other word. The second word cannot appear anywhere in the item. For example, to search for items about "aids" when you don't want the disease AIDS, type:

aids NOT disease

The items found will contain the word "aids" but not the word "disease."

Additional examples:

guns NOT hunting
albums NOT photograph

NOTE: To find out which of these techniques is available in web search engines, look for links such as Advanced Search, Search Options, or  Search Help  when searching Google, Bing, etc.. Search engines may require that you use specific symbols (e.g., plus or minus signs) instead of AND/OR/NOT, or they may require different methods for combining terms to accomplish ANDing and other search techniques.  

Phrase Searching

Most systems provide a method for you to search for a phrase - that is, to find two or more words side-by-side. This is an extremely important and powerful search technique for making sure that your search results are focused on your topic.

NOTE: Most library databases and web search engines now use quote marks. 

To search for two words side-by-side, place quotation marks around the phrase. For example,

"sex discrimination"

This ensures that the words within the quotations marks are right next to each other in the search results, rather than occurring separately and at different times within the results.

Truncation / Wildcards

Save typing by using special symbols or "wild card" characters.

Here's an example of related search terms you might want to include in a single search:

educator or educators or educational or education or educate

For this search, use the "root word." The root word is the letters these words have in common. Then, add a "wildcard character" accepted by the search system.

For example:

educat*

Truncation or wildcard characters are different in different systems, so be sure to use the correct wildcard character. For example, here are two different systems' ways of doing this search....

In Proquest: educat*
In Lexis-Nexis Academic Universe: educat!
