Nosql 对象数组的Couchbase N1QL更新查询

我是n1ql新手。我想用“ABC”搜索bucket中的所有记录，并将其替换为“DEF”。您能帮我创建这个查询和索引吗？
样本记录

{
  "userTypeNm": "pro",
  "userStateArray": [
    {
      "bindCd": "1591779772457",
      "name": "########",
      "state": "**ABC**",
      "ts": "1591779772457"
    }
  ],
  "vts": "1591779772457",
  "ets": "1591779772457",
  "daoObj": {
    "authDaObj": {
      "data": "eyJ0cmFuc2FjdGlvbklkIjoiVVNMT0dPTi0xN2U3YWQ5ZC0wN",
      "id": "829892839892"
    }
  }
}

CREATE INDEX ix1 ON default
 (DISTINCT ARRAY v.state FOR v IN userStateArray END) WHERE userTypeNm = "pro";

UPDATE default  AS d  SET usa.state = "DEF"  FOR usa IN d.userStateArray WHEN usa.state = "ABC" END
WHERE ANY v IN d.userStateArray SATISFIES v.state = "ABC" END;
