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