To perform boolean searches, use boolean operators (AND, OR, NOT) placed in ALL CAPS. Note that a hyphen (-) symbol is understood as NOT. For example, to search for research not in Spain, use: research NOT spain
To perform a wildcard search, use the (*) symbol. For example, to search for "test", "tests" or "tester", you can use the search: test*
To perform a fuzzy search, use the tilde (~) symbol at the end of a single word term. For example, to search for a term similar in spelling to "roam", use the fuzzy search: roam~
