我想通过 ES 客户端查询 crateDB。但是失败了

我在中设置es.api.enabled: true并crate.yml使用 ES java-rest-high-level-client 通过端口连接 crateDB 4200，但我无法得到任何响应

public class crateAPI {
    public static void main(String[] args) throws Exception{
        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("localhost", 4200, "http")));
        SearchRequest searchRequest =new SearchRequest();
        SearchSourceBuilder searchSourceBuilder =new SearchSourceBuilder(); 
        searchSourceBuilder.query
                     (QueryBuilders.termQuery("test.news.content","test"));
        searchRequest.source(searchSourceBuilder);
        SearchResponse searchResponse = client.search(searchRequest);
        for(SearchHit hit : searchResponse.getHits().getHits()){
            System.out.println(hit.getSourceAsString());
        }
        client.close();
    }
}

您可能不应该（并且很快就会被弃用）按照他们的官方文档中的建议在这里

但是如果你必须同时这样做，Crate 会像这样响应标准的 ES URL 搜索

http://your-server:4200/*your-index-name*/_search?q=your-field:your-search-value
