How do you "attach" the indexes to a QnA Maker Runtime?

[DanielBMann9000]

There's a comment at the top of the code that says

Once done you can attach it to the QnAMaker runtime.

However, there is no further information on how to accomplish that. I don't see anything in Microsoft's documentation on doing so, either. As it stands, this application copies the search index data without doing whatever is necessary to activate the copied data in the QNA Maker instance.
