Клиентская фильтрация FirebaseRecyclerAdapter

Question

Я использую FirebaseRecyclerAdapter для отображения посещаемости пользователей. Я хочу отфильтровать данные локально. поэтому, если пользователь нажал кнопку x в searchview, исходные результаты должны отобразиться снова.

Я пытался реализовать серверный фильтр какое-то время, но не смог, потому что adapter.notifyDataSetChanged не работает .

вот мой адаптер

package iti.intake40.mawgood_admin.reports.per_day

import android.content.Context
import android.content.Intent
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.recyclerview.widget.RecyclerView
import com.firebase.ui.firestore.FirestoreRecyclerAdapter
import com.firebase.ui.firestore.FirestoreRecyclerOptions
import iti.intake40.mawgood_admin.R
import iti.intake40.mawgood_admin.core.FirebaseConstants
import iti.intake40.mawgood_admin.reports.Report
import iti.intake40.mawgood_admin.reports.per_user.ReportPerUserActivity
import kotlinx.android.synthetic.main.reports_item.view.*

class ReportPerDayAdapter(options: FirestoreRecyclerOptions<Report>) :
    FirestoreRecyclerAdapter<Report,
            ReportPerDayAdapter.ReportsViewHolder>(options) {

    private lateinit var context: Context

    class ReportsViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView)

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ReportsViewHolder {
        val view = LayoutInflater.from(parent.context)
            .inflate(R.layout.reports_item, parent, false)

        return ReportsViewHolder(
            view
        )
    }

    override fun onBindViewHolder(holder: ReportsViewHolder, position: Int, model: Report) {

        holder.itemView.report_item_name.text = model.userName
        holder.itemView.report_item_email.text = model.userEmail
        holder.itemView.report_item_team.text = model.attend
        holder.itemView.report_item_points.text = model.lostPoints.toString()

        holder.itemView.setOnClickListener { v ->
            val intent = Intent(context, ReportPerUserActivity::class.java)
            intent.putExtra(FirebaseConstants.USER_ID, model.uid)
            context.startActivity(intent)
        }
    }

    override fun onAttachedToRecyclerView(recyclerView: RecyclerView) {
        super.onAttachedToRecyclerView(recyclerView)
        context = recyclerView.context
    }

}
