No matter what database you use to locate materials for your research, there are certain strategies that you can use in designing your searches, which will help you conduct effective searches on your research topic.
AND - combines terms; narrows and focuses search ex.: global warming and arctic
OR - used between synonyms or related terms, broadens search by supplying more options ex.: global warming or climate change
NOT - excludes terms from search, narrows and focuses search ex.: forests not tropical
TRUNCATION - symbol used at end of word or word part to retrieve variant word endings; adds flexibility and depth to your search ex: environment* retrieves: environment. environmental, environmentally, environmentalist, environmentalism, etc.
PHRASE SEARCHING - use quotes to designate phrases ex.: "climate change"
