所有索引的 Elasticsearch 计数

Question

正在尝试获取所有索引的计数。我在 URL 中使用 _all。以下代码有效，但未返回所有索引的数据。

GET /_all/_search?search_type=count&q=_type:invoice
{
  "aggs": {
    "by_index": {
      "terms": {
        "field": "_index"
      }
    }
}

}

大多数索引在输出中被跳过。索引是否有限制或我的代码有问题？

Answer 1

是的，默认返回结果的限制是10个：http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/_executing_aggregations.html.

To start with, this example groups all the accounts by state, and then returns the top 10 (default) states sorted by count descending (also default)

同样适用于terms聚合：http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#_size

在你的情况下，你需要这样的东西：

GET /_all/_search?search_type=count&q=_type:invoice
{
  "aggs": {
    "by_index": {
      "terms": {
        "field": "_index",
        "size": 0
      }
    }
  }
}
