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