An algorithm for quantum search with arbitrary unitary transformations and an arbitrary initial state was presented. Using the SU(2) representation, the matching condition relating the phase rotations in the algorithm to search a marked state with certainty was derived. A formula for evaluating the required number of iterations for the search, and the final state after the search was presented.
