• If you are trying to use Boolean operators, they must be ALL CAPS: (((("primary base medicine") OR ("primary carte medicine"))) OR ((("primary care medicine") OR ("primary case medicine")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"primary base medicine\") or (\"primary carte medicine\"))) or (((\"primary care medicine\") OR (\"primary case medicine\"))))".
• Removing quotes may allow a broader search: (((( primary base medicine ) or ( primary carte medicine ))) or ((( primary care medicine ) OR ( primary case medicine )))).
• Adding a wildcard symbol may retrieve word variants: (((("primary base medicine") or ("primary carte medicine"))) or ((("primary care medicine") OR ("primary case medicine"))))*.
