Perhaps you should try some spelling variations:
"typhoid fover" » "typhoid over", "typhoid dover", "typhoid bover"
"typhoid ever" » "typhoid every", "typhoid ver", "typhoid over"
"lymphoid fever" » "lymphoid fevery", "lymphoid fver", "lymphoid fover", "lymphoid feuer", "lymphoid feher", "lymphoid feder"
"lymphoid never" » "lymphoid nevery", "lymphoid nver", "lymphoid nover"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"typhoid fover\") OR (\"typhoid ever\"))) OR (((\"lymphoid fever\") OR (\"lymphoid never\"))))~".
• Removing quotes may allow a broader search: (((( typhoid fover ) OR ( typhoid ever ))) OR ((( lymphoid fever ) OR ( lymphoid never ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("typhoid fover") OR ("typhoid ever"))) OR ((("lymphoid fever") OR ("lymphoid never"))))*.
