• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (hoc hien)) tinh - hanh trung tuan ((nhung phuong) OR (dung phuong)) van tan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (hoc hien)) tinh - hanh trung tuan ((nhung phuong) OR (dung phuong)) van tan tap".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (hoc hien)) tinh - hanh trung tuan ((nhung phuong) OR (dung phuong)) van tan tap*.
