• If you are trying to use Boolean operators, they must be ALL CAPS: ((30 trieu) OR (((mon triet) OR (minh triet)))) tinh - hanh tang cua bang song van toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((30 trieu) or (((mon triet) OR (minh triet)))) tinh - hanh tang cua bang song van toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((30 trieu) or (((mon triet) OR (minh triet)))) tinh - hanh tang cua bang song van toan cau*.
