• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((nang x) OR (dang xay)) hoi. hieu ve ((cham xuc) OR (cham soc)) van hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((nang x) or (dang xay)) hoi. hieu ve ((cham xuc) OR (cham soc)) van hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: so sach ty ((nang x) or (dang xay)) hoi. hieu ve ((cham xuc) OR (cham soc)) van hanh vai cua te*.
