DocumentDocId Property

This is a convenience property for users that may want to attach their own unique id to the document (e.g., SQL table primary key for document). This value is not used in processing of documents other than logging. Default value is empty string (""), which indicates not set.

If this property is set on an input document (see Documents), then each child document (recursively) will have its DocId set to its parent DocId with its child index (one offset) appended. For example, if input document has DocId of "00000265", then its second child document will have a DocId of "00000265.2" (and so on, if the child document itself has child documents).
