So here’s my stab at the problem:

$filter_query[] = array(
    'relation' => 'OR',
    array(
        'column'  => 'content',
        'value'   => 'philippine tube-nosed fruit bat',
        'compare' => 'LIKE'
    ),
    array(
        'column'  => 'content',
        'value'   => 'nyctimene rabori',
        'compare' => 'LIKE'
    )
);
$retval['filter_query'] = $filter_query;

Please note I haven’t tested.
