• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thi hang ca hoi. hieu va cham tuc ((va trinh) OR (van trinh)) vi ((cua te) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thi hang ca hoi. hieu va cham tuc ((va trinh) OR (van trinh)) vi ((cua te) or (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: su sach thi hang ca hoi. hieu va cham tuc ((va trinh) OR (van trinh)) vi ((cua te) or (cua tu))*.
