• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach thu)) xang ma hoi. hieu van chat truc ban hang va ((cua tre) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach thu)) xang ma hoi. hieu van chat truc ban hang va ((cua tre) or (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) OR (sach thu)) xang ma hoi. hieu van chat truc ban hang va ((cua tre) or (cua viet))*.
