Perhaps you should try some spelling variations:
among partners » paying partners, among farmers, among parents
paciente 1.8 » paciente 2.1, pacientes 3.1, paciente con
pacienta 2.1 » paciente 2.1, pacientes 3.1, pacienta _
yang yang » wang yang, wang yan
yan yang » yao yang, dan yang, tan yang
aan de » van de, jan de
wang » wing, 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 ((yan yang) OR (yang yang)) aan de ((paciente 1.8) OR (pacienta 2.1)) among partners ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) or (yang yang)) aan de ((paciente 1.8) OR (pacienta 2.1)) among partners ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) or (yang yang)) aan de ((paciente 1.8) OR (pacienta 2.1)) among partners ;*.
