• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu va cham xuc ((van anh) or (van thanh)) sinh ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu va cham xuc ((van anh) OR (van thanh)) sinh ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu va cham xuc ((van anh) or (van thanh)) sinh ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. hieu va cham xuc ((van anh) or (van thanh)) sinh ((cua tre) OR (cuu tre))*.
