restHighLevelClient 使用nestedQuery

可以使用以下代码实现：

QueryBuilder nestedQuery = QueryBuilders.nestedQuery("path.to.nested.field", QueryBuilders.termQuery("path.to.nested.field.keyword", "value"), ScoreMode.None);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(nestedQuery);
SearchRequest searchRequest = new SearchRequest("index_name");
searchRequest.source(searchSourceBuilder);
SearchResponse searchResponse = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
