• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"typhoid fover\") OR (\"lymphoid fover\"))) OR (\"typhoid over\"))".
• Removing quotes may allow a broader search: (((( typhoid fover ) OR ( lymphoid fover ))) OR ( typhoid over )).
• Adding a wildcard symbol may retrieve word variants: (((("typhoid fover") OR ("lymphoid fover"))) OR ("typhoid over"))*.
