InDesign Script to Generate List of Words in Document

Hello, 

I am looking for the original link for a Script for word gathering and sorting in InDesign Dictionary, posted on the bottom of this page: http://www.kasyan.ho.com.ua/indesign/all/word_gathering_and_sorting_in_dictionary.html

(other scripts listed on this page throw errors in InDesign)

The link to the script was originally posted here: 

http://forums.adobe.com/thread/1177121?tstart=90

but I cannot locate.

I am interested in using this script or any script that can generate a list of words used in an InDesign document. 

Thank you very much for your assistance.
