如何通过JSON将查询设置为Elasticsearch SearchRequest？

我现在以这种方式生成SearchSourceBuilder：

String query = "..."SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();SearchModule searchModule = new SearchModule(Settings.EMPTY, false, Collections.emptyList());try (XContentParser parser = XContentFactory.xContent(XContentType.JSON).createParser(new NamedXContentRegistry(searchModule .getNamedXContents()), query)) {    searchSourceBuilder.parseXContent(parser);}
