hua west » a west, hua wei, out west
ost west » east west
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai

• If you are trying to use Boolean operators, they must be ALL CAPS: dong yang ya ((hua west) OR (ost west)) sang minh ((hong ghi) OR (hong hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang ya ((hua west) or (ost west)) sang minh ((hong ghi) OR (hong hai)) ;".
• Adding a wildcard symbol may retrieve word variants: dong yang ya ((hua west) or (ost west)) sang minh ((hong ghi) OR (hong hai)) ;*.
