• If you are trying to use Boolean operators, they must be ALL CAPS: wang managing ((large hat) OR (large cats)) ((fan xibo) OR (li ying)) hong wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang managing ((large hat) OR (large cats)) ((fan xibo) or (li ying)) hong wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang managing ((large hat) OR (large cats)) ((fan xibo) or (li ying)) hong wong sam ;*.
