• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo tieu)) sach - hanh ((tang cua) OR (ban cua)) dang song manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo tieu)) sach - hanh ((tang cua) or (ban cua)) dang song manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo tieu)) sach - hanh ((tang cua) or (ban cua)) dang song manh toan ban*.
