我的搜索:

curl -XPOST "http://localhost:9200/imoveis/_search?pretty=1" -d'
{
   "size": 0, 
   "aggregations": {
      "bairro_count": {
         "terms": {
            "field": "bairro.raw"
         }
      }
   }
}'
返回:

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "hits" : {
    "total" : 16920,
    "max_score" : 0.0,
    "hits" : [ ]
  },
  "aggregations" : {
    "bairro_count" : {
      "buckets" : [ {
        "key" : "Barra da Tijuca",
        "doc_count" : 5812
      }, {
        "key" : "Centro",
        "doc_count" : 1757
      }, {
        "key" : "Recreio dos Bandeirantes",
        "doc_count" : 1027
      }, {
        "key" : "Ipanema",
        "doc_count" : 927
      }, {
        "key" : "Copacabana",
        "doc_count" : 842
      }, {
        "key" : "Leblon",
        "doc_count" : 833
      }, {
        "key" : "Botafogo",
        "doc_count" : 594
      }, {
        "key" : "Campo Grande",
        "doc_count" : 456
      }, {
        "key" : "Tijuca",
        "doc_count" : 361
      }, {
        "key" : "Flamengo",
        "doc_count" : 328
      } ]
    }
  }
}
对于这种聚合,我有超过10个键。在这个例子中,我有145个键,我想要为他们每个人计数。有没有对桶的分页?我可以得到他们所有的吗?




curl -XPOST "http://localhost:9200/imoveis/_search?pretty=1" -d'
{
   "size": 0,
   "aggregations": {
      "bairro_count": {
         "terms": {
            "field": "bairro.raw",
             "size": 0
         }
      }
   }
}'
设置size:0在2.x以后不推荐使用,这是由于群集上存在高基数字段值的内存问题。你可以在这里阅读更多关于它的github 问题。

建议为size:1至2147483647之间的数字明确设定合理的值。
