• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc van anh ((vai cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc van anh ((vai cua) or (dai cua)) te".
• Adding a wildcard symbol may retrieve word variants: thuat sach ky ((lang xa) OR (lang ha)) hoi. hieu ve cac duc van anh ((vai cua) or (dai cua)) te*.
