<a name="kanchor309"></a>ISYSDocument:DocumentNumber Property
Returns the internal ISYS document number. Read-Only.

Syntax
[VBScript]
ReadOnly property ISYSDocument.DocumentNumber as long
[C#]
long IISYSDocument.DocumentNumber {get;}
[ColdFusion/Java]
long ISYSDocument.DocumentNumber() throws ComException;
Remarks
This number is unique to the result list, but cannot not be used as a database lookup as it will most likely change when the document is next reindexed. If you require a relationship between your database and the ISYS index, use the filename or a hash of the filename.
