• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang yan li le ((((sang minh) OR (tang min))) OR (((song min) OR (gong min)))) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yan li le ((((sang minh) or (tang min))) or (((song min) OR (gong min)))) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang yan li le ((((sang minh) or (tang min))) or (((song min) OR (gong min)))) cong shu ;*.
