How can i merge / join 2 query's and return a 0 if no record in second query

Can i merge 2 query’s in N1Ql and if one key does not exist return a 0 ? I have query’s, one is a simple query which will return the content of a array in a doc which has 2 keys, key and name and looks like this …

Query

 `select \`key\`,name from Contacts USE Keys 'activity_keys::1c721060-fbfd-4720-9e66-100fc8f4e73c'

Result

                   [  {
                        "key": "c28f7ead-d87b-4ad5-b6b3-1f204b013b50",
                        "name": "Notes Written"
                    },
                    {
                        "key": "d0181c74-22a9-4f99-9cc9-df3467c51805",
                        "name": "Pop-Bys Delivered"
                    },
                    {
                        "key": "90d142ea-6748-4781-b2b9-4f05aab12956",
                        "name": "Database Additions"
                    }]

The second query looks like this

`SELECT d.\`key\`, COUNT(1) AS count, d.name
FROM Contacts c
UNNEST c.Data d
WHERE c._type = "activity_dashboard_test"
AND c.userid = $1
AND d.date = DATE_FORMAT_STR($2 , '1111-11-11T00:00:00+00:00')
GROUP BY d.\`key\`, d.name`

And this Result looks like this

         [{
            "count": 2,
            "key": "c28f7ead-d87b-4ad5-b6b3-1f204b013b50",
            "name": "Notes Written"
        },
        {
            "count": 1,
            "key": "d0181c74-22a9-4f99-9cc9-df3467c51805",
            "name": "Pop-Bys Delivered"
        }]

So i am looking for a way to merge / join both where i want to return all from 1 query and the merge in the count value from 2nd query and if no record in 2nd return a 0 for count if posible

SELECT f.`key`, f.name, SUM(f.cnt) AS count
FROM (SELECT `key`, name , 0 AS cnt
      FROM Contacts   USE KEYS 'activity_keys::1c721060-fbfd-4720-9e66-100fc8f4e73c
      UNION ALL
      SELECT d.`key`, d.name, 1 AS cnt
      FROM Contacts c
      UNNEST c.Data d
      WHERE c._type = "activity_dashboard_test"
      AND c.userid = $1
      AND d.date = DATE_FORMAT_STR($2 , '1111-11-11T00:00:00+00:00')) AS f
GROUP BY  f.`key`, f.name;
