• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu xanh) OR (chu van)) - anh tang cua bang cong tan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu xanh) or (chu van)) - anh tang cua bang cong tan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) or (chu van)) - anh tang cua bang cong tan ((toan cau) OR (toan cao))*.
