如何使用JAVA High Level REST client发出Elasticsearch的Point InTime接口请求

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>7.15.0</version>
</dependency>

RestHighLevelClient client = new RestHighLevelClient(
        RestClient.builder(new HttpHost("localhost", 9200, "http")));

SearchRequest searchRequest = new SearchRequest("your_index");
searchRequest.source(new SearchSourceBuilder().query(QueryBuilders.matchAllQuery()))
        .scroll(TimeValue.timeValueMinutes(1));

SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
String scrollId = searchResponse.getScrollId();

while (true) {
    SearchScrollRequest scrollRequest = new SearchScrollRequest(scrollId);
    scrollRequest.scroll(TimeValue.timeValueMinutes(1));
    SearchResponse searchScrollResponse = client.scroll(scrollRequest, RequestOptions.DEFAULT);
    // 处理返回的数据
    // ...
    scrollId = searchScrollResponse.getScrollId();
    if (searchScrollResponse.getHits().getHits().length == 0) {
        break;
    }
}

ClearScrollRequest clearScrollRequest = new ClearScrollRequest();
clearScrollRequest.addScrollId(scrollId);
ClearScrollResponse clearScrollResponse = client.clearScroll(clearScrollRequest, RequestOptions.DEFAULT);
boolean succeeded = clearScrollResponse.isSucceeded();
