• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (chieu xanh)) - anh bang cua hang ((long thanh) OR (cong thanh)) khoa tai~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (chieu xanh)) - anh bang cua hang ((long thanh) or (cong thanh)) khoa tai~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) OR (chieu xanh)) - anh bang cua hang ((long thanh) or (cong thanh)) khoa tai*.
