The native docker command has an excellent way to search the docker hub repository for an image. Just use docker search <search string> to look in their registry.

However, there is a way to query the registry for all the tags in a repository, returned in JSON format. You can use a higher level programming language to get the list and parse the JSON for you. Or you can just use a simple one-liner:
# wget -q https://registry.hub.docker.com/v1/repositories/debian/tags -O - | sed -e 's/[][]//g' -e 's/"//g' -e 's/ //g' | tr '}' '\n' | awk -F: '{print $3}'

Wrap that in a little bash script and you have an easy way to list the tags of a repository. Since a tag is just a pointer to a image commit multiple tags can point to the same image. Get fancy:
# wget -q https://registry.hub.docker.com/v1/repositories/debian/tags -O - | sed -e 's/[][]//g' -e 's/"//g' -e 's/ //g' | tr '}' '\n' | sed -e 's/^,//' | sort -t: -k2 | awk -F[:,] 'BEGIN {i="image";j="tags"}{if(i!=$2){print i" : "j; i=$2;j=$4}else{j=$4" | "j} }END{print i" : "j}'
