We have searched for the decays B[superscript 0]→D[subscript s]+a[subscript 0]-, B[superscript 0]→D[subscript s][superscript *]+a[subscript 0]-, B[superscript 0]→D[subscript s]+a[subscript 2]- and B[superscript 0]→D[subscript s][superscript *]+a[subscript 2]- in a sample of about 230×10[superscript 6] Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We find no evidence for these decays and set upper limits at 90% C.L. on the branching fractions: B(B[superscript 0]→D[subscript s]+a[subscript 0]-)<1.9×10[superscript -5], B(B[superscript 0]→D[subscript s][superscript *]+a[subscript 0]-)<3.6×10[superscript -5], B(B[superscript 0]→D[subscript s]+a[subscript 2]-)<1.9×10[superscript -4], and B(B[superscript 0]→D[subscript s][superscript *]+a[subscript 2]-)<2.0×10[superscript -4].
