ElasticSearch高级查询

高级查询包含：子条件查询、复合条件查询

运行环境

{
    "OS":"centos6"
    "ES_version":5.5.2"
}

准备测试数据

向ES添加如下数据

测试数据

子条件查询

特定字段查询所指特定值，子查询又分为：Query Context、Filter Context

Query Context

概念：在查询过程中，除了判断文档是否满足查询条件外，ES还会计算一个_score来标识匹配的程度，旨在判断目标文档和查询条件匹配的程度。

Query Context有如下的常用查询：

  • 全文本查询 针对文本类型查询

    • 模糊查询

      请求地址：http://192.168.137.8:9200/book/_search

      请求方式： POST

      请求数据：

      {
      	"query":{
      		"match":{ //模糊匹配关键字
      			"title":"ElasticSearch" //匹配条件 查询title包含ElasticSearch
      		}
      	}
      }

      响应结果，title字段中包含ElasticSearch的全部查询出来了：

    • 习语匹配查询

      请求地址和请求方式不变，请求参数修改如下：

      1
      2
      3
      4
      5
      6
      7
      {
      	"query":{
      		"match_phrase":{ //习语匹配关键字
      			"title":"ElasticSearch入门" //查询条件
      		}
      	}
      }

      响应结果如下，只有title字段包含ElasticSearch入门：

      1
      2
      3
      4
      5
      6
      7

      26
      27
      {
          "took": 36,
          "timed_out": false,
          "_shards": {
              "total": 3,
              "successful": 3,
              "failed": 0
          },
          "hits": {
              "total": 1,
              "max_score": 0.7594808,
              "hits": [
                  {
                      "_index": "book",
                      "_type": "novel",
                      "_id": "8",
                      "_score": 0.7594808,
                      "_source": {
                          "author": "瓦力",
                          "title": "ElasticSearch入门",
                          "wordcount": 3000,
                          "publish_date": "2017-08-20"
                      }
                  }
              ]
          }
      }

      通过下面的例子可以更好的理解习语匹配：

      请求地址和请求方式不变，请求数据如下：

      1
      2
      3
      4
      5
      6
      7
      {
      	"query":{
      		"match":{ //模糊匹配
      			"title":"ElasticSearch入门"
      		}
      	}
      }

      响应结果如下，ES将查询条件ElasticSearch入门拆分为两个关键字ElasticSearch和入门，然后匹配所有title包含这些关键字的记录：

      1
      2
      3
      4

    • 多字段查询

      请求地址和请求方式不变，请求数据如下：

      1
      2
      3
      4
      5
      6
      7
      8
      {

Filter Context

概念：在查询过程中，只判断该文档是否满足条件，只有YES或NO。必须结合关键字bool一起使用，并且ES对Filter查询会进行缓存。示例如下：

请求地址：http://192.168.137.8:9200/book/_search

请求方式：POST

请求数据：

1

{
	"query":{
		"bool":{ //结合bool一起使用
			"filter":{ //关键字
				"term":{
					"wordcount":2000 //字数等于2000
				}
			}
		}
	}
}
