• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach ty)) sang ma hoi. hieu vu cham xuc ((va danh) or (va tinh)) tai cuc triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) sang ma hoi. hieu vu cham xuc ((va danh) OR (va tinh)) tai cuc triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) sang ma hoi. hieu vu cham xuc ((va danh) or (va tinh)) tai cuc triet".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sach ty)) sang ma hoi. hieu vu cham xuc ((va danh) or (va tinh)) tai cuc triet*.
