Pymongo對記錄進行排序時發生緩衝區溢出

-1

Pymongo對記錄進行排序時發生緩衝區溢出。我想按時間排序只滿足特定位置的記錄1。但我得到了溢出。Pymongo對記錄進行排序時發生緩衝區溢出

>>> records = db['LOG'].find({"location":"172.27.112.18"}).sort('time1', 1) 
>>> for i in records: 
...  nill.append(i) 
...

要排序對其中索引不存在的字段。在這種情況下存在的〜32 MB 的限制（見sort operations here）要解決的問題創建「時間1」作爲索引：

db.LOG.create_index([('time1', 1)])
