• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - thanh ((tung hanh) OR (tung manh)) nhung cong ban nhu cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - thanh ((tung hanh) or (tung manh)) nhung cong ban nhu cau".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) xanh - thanh ((tung hanh) or (tung manh)) nhung cong ban nhu cau*.
