1.查看集合 show collections
2.向集合中添加数据 db.runoob.insertMany([ { 'title':'data1', 'url':'http://blog.51cto.com/suyanzhu', 'description':'this is data1', 'view':5000 }, { 'title':'data2', 'url':'http://blog.51cto.com/suyanzhu', 'description':'this is data2', 'view':3650 }, { 'title':'data3', 'url':'http://blog.51cto.com/suyanzhu', 'description':'this is data3', 'view':9527 } ])
3.查看数据 db.runoob.find().pretty()
4.多条件AND查询 db.runoob.find({'title':'data1','view':5000}).pretty()
5.多条件OR查询 db.runoob.find({$or:[{'title':'data1'},{'view':{$gt:5000}}]}).pretty()
6.同时使用and和or的查询 db.runoob.find({'view':{$gt:3000},$or:[{'title':'data1'},{'description':'this is data2'}]}).pretty()
