More advanced search features

I think a function with which you could search for coins by characteristics would be a good idea. Example: looking for the smallest coin on Numista by diameter. You would simply be able to type in “sort by size - smallest to largest” and all the coins in the catalogue would appear, regardless or issuer, type or metal, arranged from smallest to largest. The same would apply for lightest to heaviest, thinnest to thickest, etc. Another function needed is to sort coins by edge, so you can look at all the coins with smooth edges, all the coins with reeded edges, all the coins with lettered edges etc.

there are probably a few more needed but I can’t think of any and I don’t want to turn this into a wall of text. Please reply if you can think of any more.
