How to query realtime database with AngularFire?

Question

how to check a specific data in realtime database as well as it checks in firestore ?

this.afs.collection('collection', ref => ref.where('data', "==", date
    )).snapshotChanges(.subscribe(res => {

I've try

this.database.list('collection', ref => ref.where

but, "Property 'where' does not exist on type 'Reference'."

I recommend checking out the AngularFire documentation on querying lists in the realtime database, and the Firebase documentation on ordering and filtering Realtime Database data in JavaScript which show that querying is done with:

this.database.list('collection', ref => ref.orderByChild("data").equalTo(date))
