• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - manh ((trung cap) OR (truong dao)) dung cong vinh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) tinh - manh ((trung cap) or (truong dao)) dung cong vinh toan ban".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) tinh - manh ((trung cap) or (truong dao)) dung cong vinh toan ban*.
