• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc hieu) or (doc hieu)) nganh - thanh ((tung cua) OR (tuong cua)) tong cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hieu) OR (doc hieu)) nganh - thanh ((tung cua) OR (tuong cua)) tong cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hieu) or (doc hieu)) nganh - thanh ((tung cua) OR (tuong cua)) tong cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc hieu) or (doc hieu)) nganh - thanh ((tung cua) OR (tuong cua)) tong cong dan than cau*.
