• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((nang xa) OR (((lang xa) OR (lang ha)))) hoi. hieu ve nam thuoc ma thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((nang xa) or (((lang xa) OR (lang ha)))) hoi. hieu ve nam thuoc ma thanh vi cua te".
