1、条件match query查询

//条件查询match query

@Testpublic void test10() throwsUnknownHostException {//1、指定es集群 cluster.name 是固定的key值，my-application是ES集群的名称

Settings settings = Settings.builder().put("cluster.name", "my-application").build();//2.创建访问ES服务器的客户端

TransportClient client = newPreBuiltTransportClient(settings)//获取es主机中节点的ip地址及端口号(以下是单个节点案例)

.addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));

QueryBuilder builder= QueryBuilders.matchQuery("interests", "changge");

SearchResponse response= client.prepareSearch("lib3").setQuery(builder).get();

SearchHits hits=response.getHits();for(SearchHit hit:hits) {

System.out.println(hit.getSourceAsString());//将获取的值转换成map的形式

Map map =hit.getSourceAsMap();for(String key:map.keySet()) {

System.out.println(key+" key对应的值为：" +map.get(key));

}

}

}

2、multimatch query查询

说明：查询的值在多个字段中进行匹配查询

//multiMatchQuery 查询的值在多个字段中进行匹配

@Testpublic void test11() throwsUnknownHostException {//1、指定es集群 cluster.name 是固定的key值，my-application是ES集群的名称

Settings settings = Settings.builder().put("cluster.name", "my-application").build();//2.创建访问ES服务器的客户端

TransportClient client = newPreBuiltTransportClient(settings)//获取es主机中节点的ip地址及端口号(以下是单个节点案例)

.addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));//第一个参数是查询的值，后面的参数是字段名，可以跟多个字段，用逗号隔开

QueryBuilder builder = QueryBuilders.multiMatchQuery("changge", "address","interests");

SearchResponse response= client.prepareSearch("lib3").setQuery(builder).get();

SearchHits hits=response.getHits();for(SearchHit hit:hits) {

System.out.println(hit.getSourceAsString());//将获取的值转换成map的形式

Map map =hit.getSourceAsMap();for(String key:map.keySet()) {

System.out.println(key+" key对应的值为：" +map.get(key));

}

}

}

3、term查询

说明：term查询是不支持分词查询的

//term查询

@Testpublic void test12() throwsUnknownHostException {//1、指定es集群 cluster.name 是固定的key值，my-application是ES集群的名称

Settings settings = Settings.builder().put("cluster.name", "my-application").build();//2.创建访问ES服务器的客户端

TransportClient client = newPreBuiltTransportClient(settings)//获取es主机中节点的ip地址及端口号(以下是单个节点案例)

.addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));//term查询是不进行分词的

QueryBuilder builder = QueryBuilders.termQuery("interests", "changge");

SearchResponse response= client.prepareSearch("lib3").setQuery(builder).get();

SearchHits hits=response.getHits();for(SearchHit hit:hits) {

System.out.println(hit.getSourceAsString());//将获取的值转换成map的形式

Map map =hit.getSourceAsMap();for(String key:map.keySet()) {

System.out.println(key+" key对应的值为：" +map.get(key));

}

}

}

4、terms查询

说明：与term的区别在于terms可以同时匹配多个条件

//terms查询：与term区别在于可以在同个字段中同时匹配多个条件，但是不支持分词

public void test13() throwsUnknownHostException {//1、指定es集群 cluster.name 是固定的key值，my-application是ES集群的名称

Settings settings = Settings.builder().put("cluster.name", "my-application").build();//2.创建访问ES服务器的客户端

TransportClient client = newPreBuiltTransportClient(settings)//获取es主机中节点的ip地址及端口号(以下是单个节点案例)

.addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));//terms查询是不进行分词的 与term的区别在terms可以指定一个字段匹配多个查询内容

QueryBuilder builder = QueryBuilders.termsQuery("interests", "changge","旅游");

SearchResponse response= client.prepareSearch("lib3").setQuery(builder).get();

SearchHits hits=response.getHits();for(SearchHit hit:hits) {

System.out.println(hit.getSourceAsString());//将获取的值转换成map的形式

Map map =hit.getSourceAsMap();for(String key:map.keySet()) {

System.out.println(key+" key对应的值为：" +map.get(key));

}

}

}

5、reange 范围查询

//reange 范围查询(日期在多少之间等)

@Testpublic void test14() throwsUnknownHostException {//1、指定es集群 cluster.name 是固定的key值，my-application是ES集群的名称

Settings settings = Settings.builder().put("cluster.name", "my-application").build();//2.创建访问ES服务器的客户端

TransportClient client = newPreBuiltTransportClient(settings)//获取es主机中节点的ip地址及端口号(以下是单个节点案例)

.addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));//rangeQurey 第一个参数为字段名，后面是范围 在设置日期格式

QueryBuilder builder = QueryBuilders.rangeQuery("birthday").from("1990-01-01").to("2000-10-10").format("yyyy-MM-dd");

SearchResponse response= client.prepareSearch("lib3").setQuery(builder).get();

SearchHits hits=response.getHits();for(SearchHit hit:hits) {

System.out.println(hit.getSourceAsString());//将获取的值转换成map的形式

Map map =hit.getSourceAsMap();for(String key:map.keySet()) {

System.out.println(key+" key对应的值为：" +map.get(key));

}

}

}
