• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chu)) xanh - canh tranh cua dung cong ((van phan) OR (van phong)) cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chu)) xanh - canh tranh cua dung cong ((van phan) OR (van phong)) cac~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chu)) xanh - canh tranh cua dung cong ((van phan) OR (van phong)) cac*.
