• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((nang xa) OR (lang xa)) hoi. hieu van chat chuc dao ((danh dai) OR (danh di)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((nang xa) OR (lang xa)) hoi. hieu van chat chuc dao ((danh dai) or (danh di)) cua tre*".
