elasticsearch过滤数组中的某个字段为空的情况

array:3 [▼
"body" => array:5 [▼
"_source" => array:21 [▶]
"query" => array:1 [▼
"bool" => array:2 [▼
"must" => array:5 [▼
0 => array:1 [▶]
1 => array:1 [▶]
2 => array:1 [▶]
3 => array:1 [▶]
4 => array:1 [▼
"nested" => array:2 [▼
"path" => "rooms"
"query" => array:1 [▼
"bool" => array:1 [▼
"must" => array:2 [▼
0 => array:1 [▶]
1 => array:1 [▼
"exists" => array:1 [▼
"field" => "rooms.room_video"
]

]
]
]
"must_not" => array:2 [▶]
]
]
"from" => 0
"size" => 10
"sort" => array:2 [▶]
目前的查询条件是这样的但是room_video始终不能排除null值
