When there do not exist the directly matched services but exist several services in the repository that can be combined to meet the requirements, how to discovery the multiple services and their composition relations are the critical issues. This paper proposes a composition-oriented and AND/OR graph-based service search method named as CoSA, which can automatically search the composition relation graph in concepts level and composition plan in implement level. Composition operator and domain characteristics are reflected in the heuristic functions. CoSA decreases the service search space and improves the search effectiveness. By unifying the service search and composition problems into one composition-oriented service search problem, CoSA enables the dynamic and automatic service composition.
