elasticsearch大部分数据一段时间后丢失字段？？

我通过mongoosastic同步数据后，后台运行一段时间后大部分数据丢失字段，请问有谁遇到过这种情况吗？？
这是丢失字段的数据：
{"took":1,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max_score":1.0,"hits":[{"_index":"albums","_type":"album","_id":"583f855125957e4dad4d3176","_score":1.0,"_source":{"uid":29240,"name":"《凯叔西游记》第二部","age":{},"tracksCnt":27,"trackStatus":"untagged","categoryId":[33],"playCnt":585,"lastTrackAt":"2016-12-01T07:16:49.735Z"}}]}}#
这是未丢失的：
