A search for the decays B+ -> h(c)K(+) and B-0 -> h(c)K(S)(0) is performed. Evidence for the decay B+ -> h(c)K(+) is found; its significance is 4.8 sigma. No evidence is found for B-0 -> h(c)K(S)(0). The branching fraction for B+ -> h(c)K(+) is measured to be (3.7(-0.9 -0.8)(+1.0 +038)) x 10(-5); the upper limit for the B-0 -> h(c)K(S)(0) branching fraction is 1.4 x 10(-5) at 90% C. L. In addition, a study of the p (p) over bar pi(+pi-) invariant mass distribution in the channel B+ -> (p (p) over bar (+)pi(-))K+ results in the first observation of the decay eta(c)(2S) -> p (p) over bar pi(+)pi(-) with 12.1 sigma significance. The analysis is based on the 711 fb(-1) data sample collected by the Belle detector at the asymmetric- energy e(+)e(-) collider KEKB at the gamma(4S) resonance.
