Perhaps you should try some spelling variations:
patients 10.5 » patients 10.6, patients 14.5, patients 10.12
patients 10.1 » patients 10.12, patients 10.6, patients 14.1
among masters » among partners, among farmers, among actors
yang yang » wang yang, wang yan
yan yang » yao yang, dan yang, tan yang
yang de » yang di, rang de, yang d
wang » wan, lang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yan yang yang de ((patients 10.1) OR (patients 10.5)) among masters ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yan yang yang de ((patients 10.1) OR (patients 10.5)) among masters ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) yan yang yang de ((patients 10.1) OR (patients 10.5)) among masters ;*.
