We study the influence of a possible coherent component in the boson source on the two-, three- and n-particle correlation functions in a generalized core-halo-type boson-emitting source. In particular, a simple formula is presented for the strength of the n-particle correlation functions for such systems. Graph rules are obtained to evaluate the correlation functions of arbitrarily high order. The importance of an experimental determination of the 4-th and 5-th order Bose-Einstein correlation function is emphasized.
