• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (thien thanh)) - canh ((manh cua) OR (ban cua)) dung phuong ban hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (thien thanh)) - canh ((manh cua) OR (ban cua)) dung phuong ban hang cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (thien thanh)) - canh ((manh cua) OR (ban cua)) dung phuong ban hang cau*.
