• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hoc thieu) OR (hoc hien))) OR (theo chieu)) xanh - thanh trung cap thang luong tai toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hoc thieu) OR (hoc hien))) or (theo chieu)) xanh - thanh trung cap thang luong tai toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((((hoc thieu) OR (hoc hien))) or (theo chieu)) xanh - thanh trung cap thang luong tai toan tap*.
