Step 5(ii): Modify your search with the truncation device

Another search technique that you can use to expand your search results is truncation.

Read the box to the right to learn how to implement this technique which may considerably boost your search results!

Step E(ii): Expand your results with truncation

Now that you have learned how to expand or narrow your results with Boolean Operators, learn how to expand your result set even further with truncation.  

Expand your results with truncation

What is truncation and how can it help expand your results?

A truncation device tells the database to search for multiple word endings of a keyword or key phrase, so you don't need to type them all.

You enter part of a keyword or key phrase and place the truncation symbol at the end. In many Discovery tools, databases, and catalogs, including GALILEO and GIL-Find, the truncation symbol is an asterisk, i.e. * The database will return results that include any ending of that partial word.

Watch the video below OR read the content in the next tab to learn how to use truncation (or do both). 

Then check out our example on the last tab.

How to use a truncation device

In most databases and catalogs, including GALILEO and GIL-Find, the truncation symbol is an asterisk, i.e. *

  1. Go back to your table of key concepts in front of you. Eg. Andy's:
  Key Concept "A" Key Concept "B"

Key Concept "C"

 

social media

Facebook

Instagram

Twitter

Snapchat

self-esteem

adolescents

teenagers

youth

 

  1. Identify the keyword or key phrase/s that can have multiple word endings which still make sense for the topic. For example, Andy identifies two keywords: 
  • teenagers  can be written as teen/s, teenage, or teenager/s
  • adolescents can be written as adolescence or adolescent/s

 

  1. Truncate (cut down) the keyword / key phrase to the point where it can start to have multiple word endings. For example:
  • teen
  • adolescen

 

  1. Input the database's truncation symbol next to it, eg. teen*, adolescen*

When the database computes:

  • teen* it will retrieve teens, teenage, teenagers
  • adolescen* it will retrieve adolescent/s, adolescence 

 

  1. Run the search. You may find an increase in results. Andy's jumped up from 52 up to 60.
