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