The search engine is not case sensitive
Irrelevant terms are ignored by the search engine
Only articles containing all search terms are retrieved by default (eg, AND is implied)
Combine multiple terms with OR to find articles containing either term; eg education OR research
Use parentheses to create more complex searches; ex .: archive ((magazine OR conference) NOT theses)
Use double quotes to retrieve the exact term; ex: "Free access to information"
Exclude terms using - or NOT; eg online -politics or online NOT policies
Use * as a wildcard; eg: soci * morality will retrieve documents containing "society" or "sociological"
