Ahh, that explains it pretty succinctly.
I personally consider this a regression with Dolphin, but it's not really a bug. When I do any searching outside of just a standard word filter, I want to see all those options easily accessible, date, size, type, what the file had for lunch...all of it.
Anyway, this isn't really the right place for that discussion. All my questions as to what is going on have been answered.
