  We perform a model-independent analysis of the data on branching ratios and
CP asymmetries of $B\to\phi K$ and $B\to\eta^{(')} K^{(*)}$ modes. The present
data is encouraging to look for indirect evidences of physics beyond the
Standard Model. We investigate the parameter spaces for different possible
Lorentz structures of the new physics four-Fermi interaction. It is shown that
if one takes the data at $1\sigma$ confidence level, only one particular
Lorentz structure is allowed. Possible consequences for the $B_s$ system are
also discussed.
