The authors report a search for the decays B{sup 0} {yields} D{sub s}{sup -}D{sub s}{sup +}, B{sup 0} {yields} D*{sub s}{sup -}D{sub s}{sup +} and B{sup 0} {yields} D*{sub s}{sup -}D*{sub s}{sup +} in a sample of 232 million {Upsilon}(4S) decays to B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage ring. They find no significant signal and set upper bounds for the branching fractions: {Beta}(B{sup 0} {yields} D{sub s}{sup -}D{sub s}{sup +}) < 1.0 x 10{sup -4}, {Beta}(B{sup 0} {yields} D*{sub s}{sup -} D{sub s}{sup +}) < 1.3 x 10{sup -4} and {Beta}(B{sup 0} {yields} D*{sub s}{sup -} D*{sub s}{sup +}) < 2.4 x 10{sup -4} at 90% confidence level.
