• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - hoang manh cua dang phuong dan ((((than tap) OR (toan tap))) OR (phan lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - hoang manh cua dang phuong dan ((((than tap) OR (toan tap))) or (phan lap))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - hoang manh cua dang phuong dan ((((than tap) OR (toan tap))) or (phan lap))*.
