Once you have developed keywords for each concept, to conduct the actual search you will want to combine these keywords using standard search operators: AND, OR and NOT. Doing so allows you to broaden or narrow your search as appropriate. There is usually no one perfect combination of keywords and you will likely run multiple searches. Consider the illustrated combination of keywords, and search operators (AND, OR, NOT) for the following:
“Discuss the impact of physical activity on the academic performance of children.”
A search using this combination will return results that include resources where physical activity, academic performance and children (or their related keywords) are present, but will exclude from those results any resources where the keyword high school is present. See the Combining Keywords Worksheet located in Resources for more examples.
