Need help with getting task list on a particular node

Sorry to post such simple request, but the new online documentation is really useless.
The reference site to old doc is also useless because the searching feature is broken.

I need to list all the tasks on a particular data node.
This command shows task list on the cluster with all the nodes:
GET /_cat/tasks/?v&detailed=true

I performed such command with parameter before so I know it exists.
I really appreciated if somebody could help me with the actual parameter to use.
The one I used before included the node's hostname (I believe).

Thanks in advance.

Never mind. I found it.
