GET_FAST_INFO 

This method does not return documents but rather information about existing documents. This information is stored in the signature table. The signature table is used to store general information and attributes. Whereas the component table contains technical information about the individual components that the documents consist of.

The application object (Document Set) is identified by the attributes described in the section Parameters.

In contrast to the method GET_INFO, the method GET_FAST_INFO does not return information about the components of the document nor does it return detailed information about all the individual documents.

Depending on the value of the parameter GET_PROPERTIES , some document attributes are returned ( GET_PROPERTIES = 'X') or no document attributes are returned.
