• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ky nang x hoi. ((hieu ve) OR (hieu van)) cam xuc ((van hanh) OR (van anh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ky nang x hoi. ((hieu ve) OR (hieu van)) cam xuc ((van hanh) or (van anh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu ban ky nang x hoi. ((hieu ve) OR (hieu van)) cam xuc ((van hanh) or (van anh)) vi cua tre*.
