• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((((ty nang) OR (ty hang))) OR (ty xang)) x hoi. hieu ve cac loc va danh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((((ty nang) OR (ty hang))) or (ty xang)) x hoi. hieu ve cac loc va danh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ((((ty nang) OR (ty hang))) or (ty xang)) x hoi. hieu ve cac loc va danh vai cua tre*.
