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