我需要根据 rep_header.share_date 或 rep_header.share_date_2 查找最近7天的记录(文档).我正在使用此代码，但不起作用:
I need to find the records (documents) from the last 7 days based on rep_header.share_date or by rep_header.share_date_2. I'm playing with this code but doesn't work:
var lastWeek = new Date();
lastWeek.setDate(lastWeek.getDate() -7);
db.messages.find({ "rep_header.share_date_2.$date": { $gte: lastWeek}} );
由于我没有结果(获取0条记录)，因此您可以看到示例文档来自 01/04 ，这是怎么回事?
Since I get no results (Fetched 0 record(s)) and as you can see the example document is from 01/04 what is wrong?
推荐答案
这是怎么回事:
db.messages.find({ "rep_header.share_date_2": { '$gte': lastWeek }} )
