ElasticSearch 分组查询

Posted 2020-11-01 jason_bo

curl -XPOST \'localhost:9200/bank/_search?pretty\' -d \'
{
  "size": 0,
  "aggs": {
    "group_by_state": {
      "terms": {
        "field": "state"
      }
    }
  }
}\'
查询结果

类似SQL中的  SELECT state, COUNT(*) FROM bank GROUP BY state ORDER BY COUNT(*) DESC
