Perhaps you should try some spelling variations:
patients 10.6 » patients 10.1, patients 10.5, patients 14.6
patients 11.6 » patients 14.6, patients 10.1, patients 10.5
among masters » among partners, among farmers, among actors
yang yang » wang yang, wang yan
yang van » yang fan, yang dean, trang van
van de » van der, van den

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: (lang OR wing) yang yang van de ((patients 10.6) OR (patients 11.6)) among masters ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(lang or wing) yang yang van de ((patients 10.6) OR (patients 11.6)) among masters ;~".
• Adding a wildcard symbol may retrieve word variants: (lang or wing) yang yang van de ((patients 10.6) OR (patients 11.6)) among masters ;*.
