What I ended up doing was using my list of indexed Items, and finding them within the text. (ctrl+f), then I opened the index palette (menu:view>show index) While I have my text selected, I clicked the add all button (the bolder box with + sign).
You have to make sure that when you create a new document, that you have the automatic text box checked, or the index won't work. Also, it's best to set up the style in which you want the index displayed after you build it-building it is probably the last thing you want to do before you publish (menu: edit>preferences>index).
What was really nice, is while we were editing the book (over and over and over) whenever an item that was indexed moved to another page, the index reference did as well.
