• If you are trying to use Boolean operators, they must be ALL CAPS: (((( chuong trinh cuay dan va caoc cap co soi viet nam ) OR ( chuong trinh ((do dan) OR (dao dan)) va ca cay cot hoi viet nam ))) OR ((( chuong trinh ((cua dan) OR (cua ban)) ca cauc cay cong oi viet nam ) OR ( chuong tinh ((cua dan) OR (cua ban)) ca cauc cay cong oi viet nam ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( chuong trinh cuay dan va caoc cap co soi viet nam ) or ( chuong trinh ((do dan) or (dao dan)) va ca cay cot hoi viet nam ))) or ((( chuong trinh ((cua dan) OR (cua ban)) ca cauc cay cong oi viet nam ) or ( chuong tinh ((cua dan) OR (cua ban)) ca cauc cay cong oi viet nam ))))~".
• Adding a wildcard symbol may retrieve word variants: (((( chuong trinh cuay dan va caoc cap co soi viet nam ) or ( chuong trinh ((do dan) or (dao dan)) va ca cay cot hoi viet nam ))) or ((( chuong trinh ((cua dan) OR (cua ban)) ca cauc cay cong oi viet nam ) or ( chuong tinh ((cua dan) OR (cua ban)) ca cauc cay cong oi viet nam ))))*.
