• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc ((luan ky) OR (luan ket)) dang xay hoi. ((hieu ve) OR (hieu van)) cau chu van thanh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc ((luan ky) OR (luan ket)) dang xay hoi. ((hieu ve) or (hieu van)) cau chu van thanh vi cua tu*".
