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