彙總一些簡單用法

由於公司須要使用一個需求, 經過用戶的當前地理位置消息搜索出周邊的一些數據, 若是使用php進行大數據計算的話,很是消耗性能,因此採用es

建立索引

PUT http://localhost:9200/showelasticsearch

建立索引字段

PUT http://localhost:9200/show/store/_mappingide

{ 
    "store": { 
            "_all":{ 
            "enabled":false 
            }, 
            "properties": { 
                "id": { 
                    "type": "integer" 
                }, 
                "name": { 
                    "type": "text",

                        }
                    }
            }
            }

建立索引文檔

PUT http://localhost:9200/show/test/2

{ 
    "id" : 1, 
    "name" :  "建升大廈", 
    "type" :  1,
    "position":{
        "location" : {
            "lat" : 22.6482057076,
            "lon" : 114.1250142233
        }
    }
}


PUT http://localhost:9200/show/test/1

{ 
    "id" : 2, 
    "name" :  "深圳市第三人民醫院", 
    "type" :  1,
    "position":{
        "location" : {
            "lat" : 22.6352587415,
            "lon" : 114.1289020619
        }
    }
}

PUT http://localhost:9200/show/test/3

{ 
    "id" : 3, 
    "name" :  "深圳百合醫院", 
    "type" :  1,
    "position":{
        "location" : {
            "lat" : 22.6164455768,
