Much of the power of Quick Fields comes from the ability to identify a type of document, and to use that categorization to determine how to process and store the document. Therefore, in most cases the bulk of processing in Quick Fields happens within the Classification stage. When configuring a session, you define the criteria for how documents will be assigned to a document class or multiple document classes, and then determine for each document class how information will be extracted from or added to the documents, and how the documents will be stored in a Laserfiche repository.
