ES5.2.2真的 支持geo排序+聚合
具体查询条件，这里不写了；
查询结果如下：

我经过实际测试es5.2.2，发现_source/_all特性很好用：
1. _source可用通过配置includes、excludes获取应用需要的field
"_source": {
          "enabled": true,
          "includes": [
            "comId",
            "name",
            "userName",
            "equips.name",
            "equips.amount"
          ],
          "excludes": [
            "phone",
            "equips.code"
          ]
        },
2.设置enabled=false关闭_source功能，关闭后，查询结果只返回doc的ID，而不会返回_source
 "_source": {
          "enabled": false,
3._all、include_in_all结合使用，是用户可用通过_all分词查询多个字段，而不需要写多个查询条件
 "mappings": {
      "testdoc03": {
        "_all": {
          "enabled": true
        },
        "_source": {
          "enabled": false,
          "includes": [
            "comId",
            "name",
            "userName",
            "equips.name",
            "equips.amount"
          ],
          "excludes": [
            "phone",
            "equips.code"
          ]
        },
        "properties": {
          "comId": {
            "type": "long"
          },
          "equips": {
            "properties": {
              "amount": {
                "type": "double",
                "include_in_all": true
              },
              "code": {
                "type": "text"
              },
              "name": {
                "type": "text",
                "include_in_all": true
              }
            }
          },
          "name": {
            "type": "text",
            "include_in_all": true
          },
          "phone": {
            "type": "keyword"
          },
          "userName": {
            "type": "text",
            "include_in_all": true
          }
        }
      }
    }
  }
 

尽管之前在很多地方都提到过，不过还是有必要单独开篇文章提醒一下大家！
Type 已经打算在6.0移除了，所以在设计 elasticsearch 的数据结构的时候，要注意到后面版本的变化。
之前在很多的文章和 PPT 都有介绍Elasticsearch 的几个核心概念，Index 对应 DB，Type 对应表，Document 对应记录，然后就真的按数据库的路子用，一个 index 里面 n 个 type 的情况大有存在，但是在 Lucene 里面其实有很多问题，所以现在es移除也是考虑了很久的。

新增参数：

index.mapping.single_type: true

 
UID 也会移除掉 _type 的值。

Type 移除大概分为两个阶段：
第一步，不支持新的索引创建多个 type，一个索引只有一个 type，名称也是固定的，不能修改。
第二步，移除。
