• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sang)) - hang hang va nhung duong manh ((toan cau) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu sang)) - hang hang va nhung duong manh ((toan cau) OR (toan tap))".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu sang)) - hang hang va nhung duong manh ((toan cau) OR (toan tap))*.
