• Performing a fuzzy search may retrieve terms with similar spellings: (((((("liver cancer") OR ("lives cancer"))) OR ("river cancer"))) OR ("oliver cancer"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"liver cancer\") OR (\"lives cancer\"))) OR (\"river cancer\"))) OR (\"oliver cancer\"))".
• Removing quotes may allow a broader search: (((((( liver cancer ) OR ( lives cancer ))) OR ( river cancer ))) OR ( oliver cancer )).
• Adding a wildcard symbol may retrieve word variants: (((((("liver cancer") OR ("lives cancer"))) OR ("river cancer"))) OR ("oliver cancer"))*.
