最近玩了一下mongdb京髓，用pymongo連接mongodb的某些查詢跟直接在mongo_cli有些不同绍移。記錄如下:
#模糊查詢
query = db.collection.find({"title": {"$regex": "xxx"}})
#多個(gè)模糊查詢
query = db.collection.find({"title": {"$regex": "xxx|yyy"}})
#過(guò)濾字段
query = db.collection.find({}, {"_id":0, "key": 1})
#時(shí)間范圍查詢
query = db.collection.find({"post_date": {"$gte": "2016-01-01"}})
query = db.collection.find({"post_date": {"$gte": "2016-01-01", "$lt": "2016-07-08"}})
