LPL 775: Statistics and Research: Search Strategies

This guide will assist students in LPL 775 with their research needs.

Search Strategies

Boolean Operators

Boolean Operators help to narrow or broaden your search. The most useful Boolean operators to connect your searches are AND, OR, NOT.

 

Boolean Search (And, Or, and Not)

 

AND finds records containing both terms. This narrows the search. For example:

  • teachers AND students
  • female AND male

OR finds records containing either one or both terms. This broadens the search. It can also be used to account for variant spellings. For example:

  • students OR learners
  • education OR pedagogy

NOT finds records containing the first term, but not the second term. This narrows the search. For example:

  • students NOT elementary
  • males NOT adolescent

You can use more than one Boolean operator in the same search.

  • technology AND elementary NOT iPad

Truncation

Truncation allows you to search various word endings simultaneously.

To use the truncation symbol enter the root of a word a and place the symbol at the end of the word.

Example 1child* will retrieve childchildschildrenchildrens, childhood

Example 2comput* will retrieve computer and computing

Refine/Limit Your Search

When searching in databases, refine your search depending on your research need. When you do this, you will get fewer results but they will be more closely related to your topic.

In this example in the Education Research Complete database, I have refined my search results to show only articles that have been peer reviewed and published in the last 5 years.
