• If you are trying to use Boolean operators, they must be ALL CAPS: ((joon chang) OR (huang ying)) can china 2 ((grain john) OR (grin john)) wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((joon chang) or (huang ying)) can china 2 ((grain john) OR (grin john)) wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((joon chang) or (huang ying)) can china 2 ((grain john) OR (grin john)) wong shiu ;*.
