I've tried in vain to find instructions on how to do a topic search. For example, if I search "baptism" I get three hits under Topic and "look it up," but they do not include my Nelsons' Bible Dictionary, which is a favorite.
So...
a. How do I do a more exhaustive topic search
b. How can I control what resources appear in the "Look it up" list of topic hits?
I'm pretty sure Nelson's has a topic for "baptism"!
