they do, otherwise /search wasn't effective, remember users not
exposed to entity id, all entities fetched by-name, so names has to
be unique.

not sure i follow, i'll assume you refer here to empty name, - you cannot have an
entity with no name.

simon, we do not have any /name today in disk, you see it in api
for backward compatibility, actually it's emulated over /alias,

and the problem is when want to search by-name, it's not included
in backend search.
