### 使用ElasticSearch <br> 控制器內置了 ``ElasticSearch`` 可以通過如下例子來調用 ``` // EDb通過傳入一個名稱來切換數據源，默認不傳是db // search有兩個參數，第一是索引名稱，第二個是查詢語句 this.EDb().search('shop',{ "query": { "match": { "name": "李四" } } }) ``` 返回 ``` { "took" : 559, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 2, "relation" : "eq" }, "max_score" : 1.89712, "hits" : [ { "_index" : "user", "_type" : "docs", "_id" : "2", "_score" : 1.89712, "_source" : { "name" : "李四", "sex" : 1, "age" : 25, "address" : "河北省" } }, { "_index" : "user", "_type" : "docs", "_id" : "4", "_score" : 0.6931471, "_source" : { "name" : "李華", "sex" : 1, "age" : 26, "address" : "河北省" } } ] } } ``` 關于ElasticSearch的語法總結，可以查看我下面這個手冊 > [ElasticSearch開發手冊](http://es.zhangyubk.com/2423818) Elasticsearch Node.js文檔 > https://www.npmjs.com/package/@elastic/elasticsearch <br>
