Perhaps you should try some spelling variations:
"typhoid fevery" » "typhoid every", "typhoid fever", "typhoid feveryy", "typhoid fvery", "typhoid fovery"
"lymphoid feveryy" » "lymphoid everyy", "lymphoid fevery", "lymphoid feveryyy", "lymphoid fveryy", "lymphoid foveryy"
"typhoid fevers" » "typhoid feverys", "typhoid fvers", "typhoid fovers"
"typhoid ever" » "typhoid every", "typhoid ver", "typhoid 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 fevery\") OR (\"lymphoid feveryy\"))) OR (\"typhoid fevers\"))) OR (\"typhoid ever\"))~".
• Removing quotes may allow a broader search: (((((( typhoid fevery ) OR ( lymphoid feveryy ))) OR ( typhoid fevers ))) OR ( typhoid ever ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("typhoid fevery") OR ("lymphoid feveryy"))) OR ("typhoid fevers"))) OR ("typhoid ever"))*.
