我是碧玉报道的新手。我尝试通过调用Java API使用来自2个缺少文档的mongodb的jasper报告生成报告。如果仅应用查找查询工作正常，但我应用排序。那个时候我遇到了异常。所以我如何解决这个问题任何人都可以帮助我。
com.mongodb.MongoQueryException：查询失败，错误代码为17144，错误消息为'Executor error：OperationFailed：Sort operat 离子使用超过最大33554432字节的RAM。添加索引，或指定较小的限制。'
我构建以下查询，
<queryString language="MongoDbQuery">
<![CDATA[{
"collectionName": "Customer_Detail",
"findQuery": $P!{whereClause},
sort:{'creditRating' : 1}
}, allowDiskUse: true]]>
</queryString>
这是完全例外
