To broaden your search, take a mental step back from your research topic and look at the big picture.

  • Just as you did when you chose your keywords identify each of the major concepts in your topic
     
  • For each concept, think of umbrella terms (that is, broader terms that your original concepts will fit under).  Then, list broader terms for your broader terms...until you can't think of a more general way to describe them. 
    • It may help to first consult a thesaurus, or do a test search to find subject headings.
    • If there isn't really a broader term for one of your concepts, don't worry.  That concept probably isn't the one that's limiting your results.
       
  • Search for the first set of broader concepts, moving on to the even broader concepts if needed!

Let's try an example. 

Suppose our topic is:  How can using Facebook help online students learn?  We tried searching for Facebook AND online students AND learning, but didn't find as much as we needed.

So, we'll identify the major concepts and list broader terms for each (and then even broader terms).

 Original concepts:

Facebook online students  learning 

 Broader concepts:

social networking or social media college students or university students  

 Even broader  concepts:

discussion or engagement or interaction students

 

 

 

Then, we'll try searching with the broader concepts:  social networking AND college students AND learning

If those keywords still don't bring enough results, we can try some of the the even broader concepts (note that you can mix and match broader and narrower terms!):  social media AND students AND learning.

 

Note: 


Broadening your search can mean broadening your research topic, too...you might decide, based on your new search results, to approach your paper or presentation in a different way.   Sometimes a slightly broader topic is more interesting to read (and to write!) about, because it includes more points of view and examples.  Be sure to clear topic changes with your instructor.

But, even when your topic is very specific, there are times when searching broadly is useful:

  • Books are typically written on broad subjects, though they may include chapters or sections on very specific topics.  You'll need to search the book catalog broadly, then look inside individual books for more specific topics.  
     
  • The same is sometimes true for websites.  A site devoted to higher education may well include a page or document about social networking in online classes, but you may have to search within the site to find it.
