我使用的是多匹配查询，如下所示的字段和查询。（ElasticSearch7.0）

GET users_index/_search
{
  "query": {
    "multi_match": {
      "query": "1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19",
      "fields": ["users.id",  "users.org", "users.email", "users.name", "posts.id"], 
      "operator": "and"
    }
  },
  "size": 25, 
  "sort": [
    {
      "posts.id": {
        "order": "desc"
      }
    }
  ]
}

字符串
有时当我的查询有更多的术语时，即使19*5 < 1024，我也会得到Query contains too many nested clauses; maxClauseCount is set to 1024错误。在计算限制时是否有其他子句起作用。这是因为ngram吗？
