1、CommonTersQuery: 指定字段进行模糊查询

//commonTermsQuery@Testpublic void test35() throws UnknownHostException{    //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 = new PreBuiltTransportClient(settings)            .addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));    QueryBuilder builder = QueryBuilders.commonTermsQuery("name","zhaoliu");    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、queryStringQuery：

　　说明：根据值去每个字段进行模糊查询 +代表必须含有  -代表不能含有

//queryStringQuery  根据值去每个字段进行模糊查询 +代表必须含有  -代表不能含有@Testpublic void test36() throws UnknownHostException{    //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 = new PreBuiltTransportClient(settings)            .addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));    //查询文档中含必须含有changge，不含有hejiu的文档（会每个字段去查询）+代表必须含有  -代表不能含有    QueryBuilder builder = QueryBuilders.queryStringQuery("+changge  -hejiu");    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、simpleQueryStringQuery  

　　说明：根据值去每个字段进行模糊查询 只要有一个符合就会返回该文章

 

 

//simpleQueryStringQuery  根据值去每个字段进行模糊查询 只要有一个符合就会返回该文章@Testpublic void test37() throws UnknownHostException{    //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 = new PreBuiltTransportClient(settings)            .addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));    //只要所有字段中，含有changge或hejiui的都返回    QueryBuilder builder = QueryBuilders.simpleQueryStringQuery("changge  hejiu");    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));        }    }}
