elasticsearch 能不能做交集查询

}

date范围：["2018-01-01", "2018-01-02") OR ["2018-01-02", "2018-01-03")

我试了这个json，报了一个错：
"type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,
    "failed_shards": [
      {
        "shard": 0,
        "index": "lbs_20190410",
        "node": "Uj-ZStATT9y66mIBIHbpKA",
        "reason": {
          "type": "i_o_exception",
          "reason": "can not write type [class java.util.HashSet]"
        }
      }
    ]
 
您遇到过吗？
 
文档上写只支持primitive types，String，Map，Array四种类型，不是这样吗
