Query: Looking for the exotic $X_0(2866)$ and its $J^P=1^+$ partner in the
  $\bar{B}^0 \to D^{(*)+} K^- K^{(*)0} $ reactions   We propose two reactions, $\bar{B}^0 \to K^0 D^{+} K^-$ and $\bar{B}^0 \to
K^{*0} D^{*+} K^-$, already measured at Belle, to look into the $J^P=0^+$,
$X_0(2866)$ state and a $1^+$ partner of molecular $D^*\bar{K}^*$ nature, by
looking at the $D^+ K^-$ and $D^{*+} K^-$ invariant mass distributions,
respectively. Very clear peaks over the background are predicted and the
branching ratios for the production of these states are evaluated to facilitate
the task of determining the needed statistics for their observation. The fact
that the $K^{*0} K^-$ mass distribution from accumulation of events of
different reactions is already available, indicates that one is not far away
from having the needed statistics to see peaks in the $D^{(*)+} K^-$ mass
distributions, so far not yet analyzed.
