下载数据文档 accounts.sjon

使用_bulk将数据索引到es集群blank索引中

curl -H "Content-Type: application/json" -XPOST "localhost:9200/bank/_bulk?pretty&refresh" --data-binary "@accounts.json"
curl "localhost:9200/_cat/indices?v"

查询所有

get bank/_search
{
    "query": {
        "match_all": {}
    }
}

指定字段查询

get bank/_search
{
    "query": {
        "match": {
            "email": "hattiebond@netagy.com"
        }
    }
}

范围查询

get bank/_search
{
    "query": {
        "range": {
            "age": {
                "gte": 20,
                "lte": 30
            }
        }
    }
}

多条件复合查询

bool 里面的 都是一些 条件 ，must 必须瞒足，should 只要要满足 minimum_should_match 个 条件是ture ，filter 只是过滤 不计入评分

get bank/_search
{
    "query": {
        "bool": {
            "must": [
                {"match": {"gender": "M"}}
            ],
            "should": [
                {"match": {"city": "Orick"}},
                {"match": {"city": "Brogan"}}
            ],
            "minimum_should_match": 1
        }
    }
}

GET /bank/_search
{
  "query": {
    "bool": {
      "must": { "match_all": {} },
      "filter": {
        "range": {
          "balance": {
            "gte": 20000,
            "lte": 30000
          }
        }
      }
    }
  }
}

分组查询

{
    "size": 0,
    "aggs": {
        "group_by_state": {
            "terms": {
                "field": "state.keyword"
            }
        }
    }
}

聚合

get bank/_search
{
    "size": 0,
    "aggs": {
        "group_by_state": {
            "terms": {
                "field": "state.keyword",
                "order": {
                    "average_balance": "desc"
                }
            },
            "aggs": {
                "average_balance": {
                    "avg": {
                        "field": "balance"
                    }
