• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((nang xa) OR (((sang ma) OR (sang tao)))) hoi. hieu van cam cuc ban banh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((nang xa) or (((sang ma) OR (sang tao)))) hoi. hieu van cam cuc ban banh vai cua tre*".
