To specify the fields to be stored, set storedFields to point to a null-delimited list of field names, terminated with a double-null. The field names in the list can contain wildcards (* and ?). A set containing a single entry "*" would match all fields, causing the text of every field to be stored in the index.
The maximum amount of text that can be stored in each stored field is controlled by dtsOptions.maxStoredFieldSize.
