• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach ky) OR (sac ky)) sang tao hoi. hieu va cam xuc ((va dan) or (va dinh)) di cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ky) OR (sac ky)) sang tao hoi. hieu va cam xuc ((va dan) OR (va dinh)) di cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ky) OR (sac ky)) sang tao hoi. hieu va cam xuc ((va dan) or (va dinh)) di cua tuc*".
