注意是index()方法 client.index(request, RequestOptions.DEFAULT); } 5.2.根据id查询文档 5.2.1.语法说明 查询的DSL语句如下: GET /hotel/_doc/{id} 非常简单,因此代码大概分两步: 准备Request对象 发送请求 不过查询的目的是得到结果,解析为HotelDoc,因此难点是结果的解析。完整代码如下: 可以看到,结果是一个...

1.什么是 ElasticSearch? Elaticsearch,简称为es, es是一个开源的高扩展的分布式全文检索引擎,它可以近乎实时的存储、检索数据;本身扩展性很好,可以扩展到上百台服务器,处理PB级别的数据。es也使用 Java 开发并使用Lucene作为其核心来实现所有索引和搜索的功能,但是它的目的是通过简单的RESTful API来隐藏 Lucene 的复...
