To get better results use * to get all words from a root.
Example: Searching for child* will find results containing child or children
When you are searching a concept that is expressed with more than one word, use quotation marks to ensure more accurate results.
Example: "sexual assault"
It's good to be aware that results published in the United States might use a different spelling than you are used to in Canada. Use OR to make sure you are getting results with Canadian/British spelling and American spelling.
Example: "organizational behavior" OR "organizational behaviour"
