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