**2.9 返回name中包含"海",且地址不是"山东烟台"的所有document**

POST /school/_search
    {

            { "match": { "address": "山东烟台" } }
          ]
        }
      }
    }

**查询结果:**

{

      "_shards": {
        "total": 3,

            }
          }
        ]
      }
    }

**3. 过滤查询**

3.1 在所有document中寻找age在0-25岁之间(闭区间)的学生

POST /school/_search
    {
      "query": {
        "filtered": {
          "query": { "match_all": {} },
          "filter": {
            "range": {
              "age": {
                "gte": 0,
                "lte": 25
              }
            }
          }
        }
      }
    }

**4.谈论query和filter的效率**

一般认为filter的速度快于query的速度   
 \- filter不会计算相关度得分，效率高   
 \- filter的结果可以缓存到内存中，方便再用
