Use quotation marks around a phrase to retrieve results that include the exact phrase - for example "body image" or "genetic engineering" or "third culture kid".
When searching for a keyword with multiple variations (ex. "child", "children", "childhood", etc.) use the root form of the word with an asterisk (the little * symbol). Using child* will retrieve all keyword variations-- child, children, childhood.
Be specific: A search for child* and media and violence is much better than one for television violence
Use the various ways of limiting a search that appear on your results screen - most interfaces let you limit by publication date, subject, format and more. Use these to narrow your results list as much as possible.
