database - SQL LIKE operator in Cloud Firestore?

I have been using Firebase Real Time Fatabase for a while and I come across Cloud Firestore today. I can't figure out on how to use LIKE operator on Firestore.

Firebase Real Time Database

ref.child('user').orderByChild('name').startAt(name).endAt(name+'uf8ff')

On Cloud Firestore, I have tried

userRef.where('name', '>=', name); <br>
userRef.where('name', '<=', name);

But it doesn't work.
