Example: "Justification", searching using the Systematic Theology Concept in the Factbook in the Web App, it does not register any resource (in my case) and one I really would like to have reference is Boyce's Abstract of Systematic Theology as it has a chapter named "Justification" (Chapter 35 or XXXV)

Also the same happens with other systematic theologies I own (a small list):

1) Studies in Dogmatics: Faith and Justification - Berkower (Chapter VI for sure)
2) Systematic Theology (Berkhof) - IX Justification and other chapters
3) Systematic Theology: Biblical, Historical, and Evangelical, Volume 2 (Garrett, James Leo, Jr.) - Chapter 60

And others... none of my resources show any entries on my library for "Justification". That in the section named "Books fromyour Library" and there are no results given

I think it used to work better in L8
