• If you are trying to use Boolean operators, they must be ALL CAPS: va sac ky nang ((ma hoi) OR (mai hoi)). lieu ly nam thuc ((va thanh) OR (gia thanh)) vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va sac ky nang ((ma hoi) OR (mai hoi)). lieu ly nam thuc ((va thanh) or (gia thanh)) vai cua te".
• Adding a wildcard symbol may retrieve word variants: va sac ky nang ((ma hoi) OR (mai hoi)). lieu ly nam thuc ((va thanh) or (gia thanh)) vai cua te*.
