Search question

I am going through Schwandt's Learning Biblical Greek and would like to print out the exercises at the end of chapter so I can do some actual work with pen and paper. If I do a proper search I can print/export the filtered text.

What's the easiest way to get just those sections?

I can search largetext/heading:exercise which gets me close, but it doesn't include any of the text within those articles.

Suggestions?
