Alright, I've found that issue too. The way I fixed it, is by adding mAdapter.notifyDataSetChanged(); in the FindUsersActivity file.

The code should look something like this:
mSearch.setOnClickListener(new View.OnClickListener() {
@OverRide
public void onClick(View view) {
//Before searching in database, it requires to clear the data.
clear();
mAdapter.notifyDataSetChanged();
//Searching for user by email
listenForData();
}
});
