etp::create_search_impl (public)

 etp::create_search_impl -content_type content_type

Creates and registers a service contract implementation alias for an ETP custom application type if it does not already exist. This will define the datasource proc for the type as etp::revision_datasource. That proc will attempt to call a specially named tcl proc of the form etp::content_type where content_type is the acs_object type of the content type. If the proc does not exist only the attributes of the default type will be used to create the datasource.
