checking substring from firebase and retriving data

Question

I want to check weather string i have is substring of Treats field and if yes then how to retrive data of remaining fields and display it. i want to do this for all doctors.

The Firebase Database doesn't support queries that search for a substring. If this functionality is required for your app, consider using another/additional service.

You would have to loop through each doctor and check if your string is a substring. Save each doctor that has your substring and display the rest of their data.

After setting up firebase for your project and adding all of the SDKs (if you haven't done that yet, do that here), you can retrieve data by using this:

for(var i = 0; i < 2; i++){
var postId = i
var findTreat = firebase.database().ref('Doctor/' + postId + '/Treats');
  findTreat.on('value', function(snapshot) {
  updatefindTreat(postElement, snapshot.val());
});
}

I found this using the firebase docs. Let me know if this works!
