• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - hanh trang cua nhung cong san ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - hanh trang cua nhung cong san ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - hanh trang cua nhung cong san ((toan cao) or (toan tap))*.
