I am curious if anyone is using Deskrule? It looks like it can search the contents of a file [...]

I was interested in Deskrule because it can do obscure searches like finding which of your JPEGs does
not have your name in the copyright field of its EXIF data. The problem is that I find Deskrule one of the most impenetrable programs I've ever tried to use. A GUI where you can tear bits off and dock them somewhere else does not help me, and I think it makes Help more confusing, because there's no guarantee your version will have the same appearance as is shown in Help. I hate online Help anyway, the more so when it forces Edge, a browser I never use, and which isn't even set as my default. It wasn't just me that had problems with the UI, either. At one point the author revised Deskrule to offer an alternative interface that was supposed to be easier. I didn't find it much improvement, or maybe I was just jaundiced by then and didn't persevere. Hence it may be the most powerful search engine ever made, but remains a mystery to me. I'd rather have the relatively simple and straightforward UIs of programs like Nir Sofer's
SearchMyFiles or the search part of
XYplorer or maybe Binary Fortress'
FileSeek.
