Indexing Server Document Properties

[11JTH11]

I have an asp script that queries an IIS INdexing Service catalog. Everything works fine, except I want to add a document property to the list of column names that I wish to return. In this case the property name is 'Hyperlink Base' - which can be seen by opening a word doc and checking our the properties. However, I can't seem to find any docco telling what the name of the property is, or even if it can be returned. For example, the document title can be referred to as DocTitle, the comments as DocComments, etc etc.

Any Help would be much appreciated....
