• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (cho chu)) xanh - hanh trung trinh bang cong san ((than cao) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (cho chu)) xanh - hanh trung trinh bang cong san ((than cao) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (cho chu)) xanh - hanh trung trinh bang cong san ((than cao) or (toan cao))*.
