• If you are trying to use Boolean operators, they must be ALL CAPS: ((nuoc sach) OR (thuat sach)) y tang ma hoi. hieu ve coc luc va danh ((vai cua) OR (lai cua)) viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nuoc sach) or (thuat sach)) y tang ma hoi. hieu ve coc luc va danh ((vai cua) OR (lai cua)) viet~".
• Adding a wildcard symbol may retrieve word variants: ((nuoc sach) or (thuat sach)) y tang ma hoi. hieu ve coc luc va danh ((vai cua) OR (lai cua)) viet*.
