I am working on a project which has some private information. They are indexed in google and is showing as a snippet. Now I want to remove those URL from google index. I have gone through the google webmaster tool and followed instruction given to remove url

Following is the URL I want to remove :

- https://www.example.com/cars/first-car
- https://www.example.com/brands/first-brand/computers/first-computer/

Above are dynamic URLs.

Following is what I have entered for removal : (Google is showing removed in webmaster)

- https://www.example.com/cars
- https://www.example.com/brands

What I believe is it should remove all the URLs which have root /cars and /brands from Google about my website.

But it is still showing in the Google index.

I want to know that if I enter following :

- https://www.example.com/cars/*
- https://www.example.com/brands/*

Will that work? if not what I should enter to remove all that URLs and snippet to prevent showing on google? Your help will be appreciated.
