具体的Search_after解释，可以看我这篇文章 elasticsearch 深度分页查询 Search_after（图文教程）

一. 代码

public class Test {public static void main(String[] args) throws IOException {// 创建客户端final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY,new UsernamePasswordCredentials("elastic", "chenyunzhi"));// 跳过ssl验证SSLFactory sslFactory = SSLFactory.builder().withUnsafeTrustMaterial().withUnsafeHostnameVerifier().build();RestClientBuilder builder = RestClient.builder(new HttpHost("192.168.1.47", 9200,"https")).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {@Overridepublic HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {return httpClientBuilder.setSSLContext(sslFactory.getSslContext()).setSSLHostnameVerifier(sslFactory.getHostnameVerifier()).setDefaultCredentialsProvider(credentialsProvider);}});// Create the transport with a Jackson mapperElasticsearchTransport transport = new RestClientTransport(builder.build(), new JacksonJsonpMapper());// 客户端连接ElasticsearchClient client = new ElasticsearchClient(transport);// 创建pitOpenPointInTimeRequest.Builder build = new OpenPointInTimeRequest.Builder();OpenPointInTimeRequest.Builder builder1 = build.index("test-000005").keepAlive(new Time.Builder().time("1m").build());OpenPointInTimeResponse openPointInTimeResponse = client.openPointInTime(builder1.build());String id = openPointInTimeResponse.id();// 构造查询条件SearchRequest.Builder sort = new SearchRequest.Builder().size(5).pit(p->p.id(id).keepAlive(k->k.time("1m"))).sort(s -> s.field(f -> f.field("name.keyword").order(SortOrder.Desc)));// 获取第一次查询的结果List<Hit<HashMap>> hits = client.search(sort.build(), HashMap.class).hits().hits();// 检查 hits 列表是否为空if (!hits.isEmpty()) {//  获取最后一个值的sortList<String> sort1 = hits.get(hits.size() - 1).sort();// 再次构造查询条件 加上searchAftersort = new SearchRequest.Builder().size(5).pit(p->p.id(id).keepAlive(k->k.time("1m"))).searchAfter(sort1).sort(s -> s.field(f -> f.field("name.keyword").order(SortOrder.Desc)));List<Hit<HashMap>> hits1 = client.search(sort.build(), HashMap.class).hits().hits();System.out.println("-------------------------第一次查询结果-------------------------");System.out.println(hits);System.out.println("-------------------------最后一个值的sort-------------------------");System.out.println(sort1);System.out.println("-------------------------第二次查询结果-------------------------");System.out.println(hits1);}// 关闭client.closePointInTime(c->c.id(id));transport.close();}
}
