一、现象

1、查询语句
GET goods/_search
{
  "from": 0,
  "size": 10,
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "couponIds": [1,2]
          }
        }
      ]
    }
  }
}
2、错误现象
{
  "error" : {
    "root_cause" : [
      {
        "type" : "parsing_exception",
        "reason" : "[term] query does not support array of values",
        "line" : 9,
        "col" : 26
      }
    ],
    "type" : "parsing_exception",
    "reason" : "[term] query does not support array of values",
    "line" : 9,
    "col" : 26
  },
  "status" : 400
}

二、原因

数组查询要用关键字terms ，不是term

三、解决

GET goods/_search
{
  "from": 0,
  "size": 10,
  "query": {
    "bool": {
      "must": [
        {
          "terms": {
            "couponIds": [1,2]
          }
        }
      ]
    }
  }
}
