Return entry where matrix field is not empty I am trying to get a random entry which has the quote matrix field populated.

I've tried this:

{% set entry = craft.entries.section('entries').quote(':notempty:').order('RAND()').limit(1) %}


That isn't working. What do I need to do?
Currently the only way to find entries that have Matrix rows is with the search param:

{% set entry = craft.entries.section('entries').search('quote:*').order('RAND()').limit(1) %}
