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