Digital Workshop

Hi,
I'm wondering if there is a script that would achieve the following scenario:

When the publication user is on a page located in chapter 1 and uses the search function, it only displays keywords found on pages in chapter 1. However, if he goes to a page in chapter 2 and uses the search function, it only displays keywords found on pages in chapter 2.

I would bet that it is not possible, but no harm in asking, right?

Thanks a lot,
Mike
