Delete multiple records using mongoimport

I strongly recommend that you take M001 course from https://university.mongodb.com/. That sort of things are well covered. For you requirement you might try:

C:\Users\Jagadeesh> mongo Address-Of-Your-Server
// The mongo shell is started
>
// Select the database you what to use
> use test 
// Simply delete the documents with
> db.collectionName.deleteMany( { "resource":"xxx" , "channel.ItemId":"yyy" } )
