How to Search Within Sections of Commentaries

Dan Starcevich

I remember a Training Blog tutorial on how to search within sections of commentaries but of course can't seem to find it.  For example, I am studying Colossians right now and want to search within the introductions for background on the problem in the church.  Can someone remind me how to construct such a search?  

TIA
