elasticsearch:错误的计数方面

时间:2013-07-01 10:29:28

标签: curl elasticsearch

不确定这是错误还是我遗漏了什么。但是,条款方面对于条款数量的返回计数错误。

我的字段有str_tag_analyzer

我想从字段中获取Tag Cloud。我想获得前20个标签以及他们的计数(他们出现了多少次)

术语方面看起来是这种情况的解决方案。我理解,术语构面查询中的大小参数控制将返回多少个标记。

当我运行不同大小的术语构面查询时,我得到意想不到的结果。以下是我的一些疑问及其结果。

查询1

      } ]
    }
  }
}

}'
{

  "timed_out" : false,
  "_shards" : {
    "total" : 3,
    "successful" : 3,
    "failed" : 0

    "max_score" : 1.0,
    "hits" : [ ]
  },
  "facets" : {
    "tags" : {
      "_type" : "terms",
      "missing" : 57,
      "total" : 331,
      "other" : 198,
      "terms" : [ {
        "term" : "playing",
        "count" : 20
      }, {
        "term" : "hyderabad",
        "count" : 19
      }, {
        "term" : "bangalore",
        "count" : 18
      }, {
        "term" : "pune",
        "count" : 16
      }, {
        "term" : "chennai",
        "count" : 16
      }, {
        "term" : "games",
        "count" : 13
      }, {
        "term" : "testing",
        "count" : 11
      }, {
        "term" : "cricket",
        "count" : 9
      }, {
        "term" : "singing",
        "count" : 6
      }, {
        "term" : "movies",
        "count" : 5
      } ]
    }
  }
}

我有以下顾虑 1.第一个查询给出计数为15的标记,但是存在另一个计数为20的标记(可以在查询2和3中看到)。所以它必须返回计数为20的“播放”标签。 2.第二个查询将“hyderabad”标记的计数返回为15,但对于同一标记,第三个查询返回计数为19。

如果您需要任何其他信息,如ES中的数据,请告知我们。 谢谢

这是一个known issue。解决方法是使用单个分片或询问您打算显示的更多术语。
