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