• If you are trying to use Boolean operators, they must be ALL CAPS: qian yan fang a ((((cheng ton) OR (cheng han))) OR (cheng boon)) minh wing sun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan fang a ((((cheng ton) OR (cheng han))) or (cheng boon)) minh wing sun ;~".
• Adding a wildcard symbol may retrieve word variants: qian yan fang a ((((cheng ton) OR (cheng han))) or (cheng boon)) minh wing sun ;*.
