dong yang » dong hoang, wang yang, yang yang
dong nan » dong sin, dong bin, dong cao
case how » curse how, case h, else how
how yu » how you, how your
ya du » a du

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong nan) OR (dong yang))) OR (wang yan)) ya du credit trade case how yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong nan) OR (dong yang))) or (wang yan)) ya du credit trade case how yu ;*".
