• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu tinh) OR (lieu tinh)) - canh tranh cua nong thong ((van toan) OR (ban hang)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (lieu tinh)) - canh tranh cua nong thong ((van toan) or (ban hang)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) OR (lieu tinh)) - canh tranh cua nong thong ((van toan) or (ban hang)) cau*.
