for example I have collection_1 with this data: "_id": "60d75ed08af96529bf605030" "Fname": "some name" "Lname": "some last name" "Age": "20" "sex": "Woman" "Previous_job": "Arsen"

and collection two with this data: "_id": "60d75ed08af96529bf605030" "Fname": "some name" "Lname": "some last name" "Age": "20" "sex": "Woman" "Previous_job": "Arsen"

I know how I can make it in MySQL using UNION ALL but I don't know how to make it in mongo db, how can I combine these collections in one collection? can give answer in Russian or Ukraine
