I didn't notice this until I started searching relationship types, but when I do so, it seems that some relationships are subtypes of other relationships. in this example, "instruments" and "editor" appear to be subtypes of "DJ-Mixed", which I know is wrong:

could be fixed by simply un-indenting everything when searching, or always showing the parent type. I think I lean more towards the former myself though

there's also odd ordering sometimes, I'd expect items starting with an "i" in this search above everything simply containing an "i". that may be outside the scope of this ticket tho...
