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