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