        The Schematic Search Diagrams operation is performed on the schematic
        service resource. The result of this operation is an array of Schematic
        Diagram Information Object.

        It is used to search diagrams in the schematic service by criteria;
        that is, diagrams filtered out via a where clause on any schematic
        diagram class table field, diagrams that contain schematic features
        associated with a specific set of GIS features/objects, or diagrams
        that contain schematic features associated with the same GIS features/
        objects related to another set of schematic features.
