ansible task failing to search a string in list output from ansible shell result

Question

Team, I have below task but I need to search for sdd in its output which is a list. listing the output and my assert is failing. I just want to print a message sdd found and not found on this task based on result.

#Local volume provision sdd check on CPU node
      - name: "Verify LVP Mounts sdd exists on CPU Nodes for mount_device"
        shell: "mount | grep sdd"
        register: lvp_mount
        ignore_errors: yes
        failed_when: False
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-cpu-node'] }}"

      - set_fact:
          sdd: lvp_mount.results[0].stdout_lines
        when: lvp_mount is succeeded
      - debug:
          var: lvp_mount.results[0].stdout_lines
      - debug:
          msg: "Assert SDD Mounts present"
        failed_when: lvp_mount.results[0].stdout_lines[0] is search('sdd')

output

My bad, I was doing opposite of logic. Need to do NOT. is not search('sdd')

      - name: "Verify LVP Mounts sdd exists on CPU Nodes for mount_device"
        shell: "mount | grep sdd"
        register: lvp_mount
        ignore_errors: yes
        failed_when: False
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-cpu-node'] }}"
      - debug:
          msg: "Assert SDD Mounts present"
        failed_when: lvp_mount.results[0].stdout_lines[0] is not search('sdd')
