Java AppEngine JDO查询未按预期工作

我正在使用AppEngine，我想查询以下数据实体：

• 布尔数据“可选”为False
• 日期“registrationTimestamp”的升序

我的代码：

Query query = pm.newQuery(DeviceInfo.class);
query.setFilter("optional == False");
query.setOrdering("registrationTimestamp asc");
List<DeviceInfo> datas = (List<DeviceInfo>)query.execute();

Query Query=pm.newQuery（DeviceInfo.class）；
setFilter（“可选==False”）；
query.setOrdering（“registrationTimestamp asc”）；
List data=（List）query.execute（）；

当我看到数据时，有数据显示“optional”为True。我想筛选出“可选”为真的条目。setFilter（“可选==False”）似乎不起作用

如何执行所需的查询

编辑

我得到了DataNucleus建议的调试级别的日志

希望能有所帮助

，日志上说查询结果如何？@DataNucleus，当setFilter或setOrdering不被接受时，我发现索引找不到异常。但对于问题中显示的查询，我没有得到异常，没有错误日志。但我确实在查询结果中看到了“optional==True”数据。因此，我认为setFilter不起作用。日志会告诉您使用的是什么低级查询。@DataNucleus，日志说：com.google.appengine.api.datastore.QueryResultsSourceImpl logChunkSizeWarning:此查询在FetchOptions中没有设置块大小，返回了1000多个结果。如果此大小的结果集对于该查询是常见的，请考虑设置块大小以提高性能。要禁用此警告，请在appengine-web.xml中设置以下系统属性（该属性的值无关紧要）：“appengine.datastore.disableChunkSizeWarning”，但不显示查询信息。调试时，我在调试级别显示日志您提供的是低级数据存储API。我想改用JDO。

Query q = new Query("DeviceInfo")
            .addFilter("optional",
                       Query.FilterOperator.EQUAL,
                       false);
