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