• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hiem) OR (hoc thiet)) ngan - thanh truong cao nong cong tan ((thanh chau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hiem) OR (hoc thiet)) ngan - thanh truong cao nong cong tan ((thanh chau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hiem) OR (hoc thiet)) ngan - thanh truong cao nong cong tan ((thanh chau) or (than cap))*.
