On a coreOS (899.15.0) machine, when I execute docker search and images I get the following results :

docker search private-registry:5000/ 

NAME      DESCRIPTION   STARS     OFFICIAL   AUTOMATED

docker images on the private registry machine:

REPOSITORY                                                      TAG                 IMAGE ID                                                           CREATED             VIRTUAL SIZE

...and a few more images

The reference for docker search mentions that it looks up on docker hub, but since I am specifying a specific registry here, I suppose it is looking up in the private repository.

I am not sure what is the difference between these two commands here and why the difference in results.

You are supposing wrongly. docker search searches only Docker Hub, not private registries. docker images command lists images on the machine (locally built or pulled from registries).

If you want to search or list images in the private registry, you need to use registry API to do so: https://docs.docker.com/registry/spec/api/
