• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo tieu)) xanh - anh hang va dung cong van ((nhan tai) OR (van tai)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) xanh - anh hang va dung cong van ((nhan tai) OR (van tai))".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo tieu)) xanh - anh hang va dung cong van ((nhan tai) OR (van tai))*.
