我正在尝试根据 totalEmployee 字段对文档进行排序，其中索引是index_db，类型是部门，字段是totalEmployee
QueryBuilder qb = QueryBuilders.matchAllQuery();
SearchResponse response = client.prepareSearch("index_db").setTypes("departments")
.addSort(SortBuilders.fieldSort("totalEmployee").order(SortOrder.ASC)).setQuery(qb)
.setSize(100).execute().actionGet();
for(SearchHit hits :response.getHits()) {
System.out.print("id = "+hits.getId());
System.out.println(hits.getSourceAsString());
}
但我收到错误：
