• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (25 trieu)) tinh - ((hanh mang) OR (hanh trang)) va dung cong tan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - ((hanh mang) or (hanh trang)) va dung cong tan toan ban".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - ((hanh mang) or (hanh trang)) va dung cong tan toan ban*.
