elasticsearch 关于nested筛选，根据inner_hits的长度过滤数据怎么实现

查询语句是：

{"from":0,"size":100,"search_after":[0],"query":{"bool":{"must":[{"term":{"sex":"女"}},{"range":{"age":{"gte":30,"lte":40}}},{"bool":{"should":[{"bool":{"must":[{"match_phrase":{"province":"辽宁省"}},{"match_phrase":{"city":"沈阳市"}}]}},{"bool":{"must":[{"match_phrase":{"province":"辽宁省"}},{"match_phrase":{"city":"抚顺市"}}]}}]}},{"nested":{"path":"orders","inner_hits":{"from":0,"size":100},"query":{"bool":{"must":[{"range":{"orders.bookingTime":{"gte":"1970-01-01 08:00:00","lte":"2021-08-13 23:59:59","format":"yyyy-MM-dd HH:mm:ss"}}},{"terms":{"orders.ticketId":[530535]}},{"terms":{"orders.bookingChannelId":[19]}}]}}}}]}},"sort":"_id","_source":{"excludes":["orders"]}}

我想实现只返回inner_hits里面_source数组长度为1的数据。
