• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - ((thanh trung) OR (thanh tung)) va ((nhung tuong) OR (nhung phuong)) van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - ((thanh trung) or (thanh tung)) va ((nhung tuong) OR (nhung phuong)) van toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - ((thanh trung) or (thanh tung)) va ((nhung tuong) OR (nhung phuong)) van toan cao*.
