• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang xa) OR (nang ma)) hoi. hieu van ((phu tho) OR (cam xuc)) van thanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang xa) OR (nang ma)) hoi. hieu van ((phu tho) OR (cam xuc)) van thanh vai cua tre*.
