• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky danh) OR (ky nang)) ((xay hoi) OR (xa hoi)). hieu va cam loc va thanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky danh) or (ky nang)) ((xay hoi) OR (xa hoi)). hieu va cam loc va thanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ((ky danh) or (ky nang)) ((xay hoi) OR (xa hoi)). hieu va cam loc va thanh vai cua te*.
