According to the available documentation this code was authored by Mark Kuschnir. Is there a way to obtain the source code?
If you are using Tamino 4.4.x and a current version of MS Word, you could just create a Tamino collection and define the XML Schemas for the Word XML format and then map a Tamino WebDAV folder to that collection. Word supports WebDAV locations for storing and retriving the documents and if you use the XML format of Word, you could store the documents as XML and also use Taminos XML processing functionality, e.g. via XQuery, to search in the documents or even modify them.
