• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thien) OR (hoc hien)) danh - hanh ((truong cua) OR (truong quan)) thong cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc hien)) danh - hanh ((truong cua) OR (truong quan)) thong cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc hien)) danh - hanh ((truong cua) OR (truong quan)) thong cong dan than cau*.
