noSQL Search Query

Besides using _ID to do searching, you can also use other fields or multiple fields to do searching. For example:

Examples JavaScript Codes
By username   db.collection(“comments”).find( {username: “Peter”} , {limit: 1000}).asArray()  

It will search all comments with username = “Peter”  

By Date   db.collection(“comments”).find( { date: “01/01/2018”} , {limit: 1000}).asArray()  

It will search all comments with date = “01/01/2018”.  
By both Username and Date   db.collection(“comments”).find( {username: “Peter”, date: “01/01/2018”} , {limit: 1000}).asArray()  

It will search all comments with username = “Peter” and date = “01/01/2018”.  

You see, it is very simple to write such noSQL query.
