By default, `docker search` will only search from Docker Hub, but to a search different registry, you can add the registry address before the search term, for example, `docker search quay.io/hello`. Alternatively, you can use the registry's web pages to search for images. Take a look at the page of [the `nordstrom/hello-world` image on Quay](https://quay.io/repository/nordstrom/hello-world). The page shows the command to use to pull the image, which reveals that we can also pull images from hosts other than Docker Hub:
