Deep search fields...
I have been doing some experimentation with the deep search feature & I noticed something interesting. When specifying the minting authority, you curently have 4 choices in deep search: authority, emperor, king & ruler. As far as I can tell "authority", "emperor" and "ruler" give the same results each time & are probably just redundant (i.e. couldn't you just use "ruler" with all coin templates?). The "king" field gives me no results...is this just a dead-end, or does it relate to future templates?
Bottom line: It would seem that just one "ruler/authority" choice would be less confusing for users than trying to decide the differences between king, emperor, ruler and authority.
