The input set includes all of the source documents that a particular job will process. Documents are added to the job's input set through the Input Files tab on the Job Builder dialog. The input set can include any combination of individual documents, folders, and saved searches. When you add a folder, only the documents at the root of the folder are processed by the job. When you add a saved search, the job will process all the documents found in the search. Input sets cannot contain documents from multiple datasources; if you need to process documents from multiple datasources, create a job definition for each datasource.
