Perhaps you should try some spelling variations:
"typhoid fevery" » "typhoid every", "typhoid fevers", "typhoid feveryy", "typhoid fvery", "typhoid fovery"
"lymphoid fevery" » "lymphoid every", "lymphoid fevers", "lymphoid feveryy", "lymphoid fvery", "lymphoid fovery"
"typhoid fever" » "typhoid fevery", "typhoid fver", "typhoid fover"
"lymphoid ever" » "lymphoid every", "lymphoid ver", "lymphoid over"

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 fever\") OR (\"typhoid fevery\"))) OR (((\"lymphoid fevery\") OR (\"lymphoid ever\"))))~".
• Removing quotes may allow a broader search: (((( typhoid fever ) OR ( typhoid fevery ))) OR ((( lymphoid fevery ) OR ( lymphoid ever ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("typhoid fever") OR ("typhoid fevery"))) OR ((("lymphoid fevery") OR ("lymphoid ever"))))*.
