• Performing a fuzzy search may retrieve terms with similar spellings: (((("given public relations.") OR ("en public relations."))) or ("german ethnicity questions."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("given public relations.") OR ("en public relations."))) OR ("german ethnicity questions.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"given public relations.\") OR (\"en public relations.\"))) or (\"german ethnicity questions.\"))".
• Removing quotes may allow a broader search: (((( given public relations. ) OR ( en public relations. ))) or ( german ethnicity questions. )).
• Adding a wildcard symbol may retrieve word variants: (((("given public relations.") OR ("en public relations."))) or ("german ethnicity questions."))*.
