Save Fragment State & restore it - android-fragments

Question

I'm trying to develop an app, I've a problem with fragment's state. Main Activity has 2 fragments added using view pager, one of them is used to do search in database, the result (which is like headers) is displayed in a recycler view, on recycler view item click a new fragment is displayed with a web view, just like the picture
My prob is when I rotate screen everything is wiped, & it only displays my search query.
That's Search fragment Layout
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<SearchView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/InterSearchView"
android:iconifiedByDefault="false"
android:layout_marginTop="10dp"
android:layout_marginStart="20dp"
android:layout_marginEnd="20dp"
android:queryHint="#string/search_here"/>
<ScrollView
android:id="#+id/BySearch_Scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/InterSearchView"
android:layout_marginTop="10dp"
android:layout_marginStart="20dp"
android:layout_marginEnd="20dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/BySearch_Recycler"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/Search_BySearch_Frag"
android:layout_below="#id/BySearch_Recycler"
android:layout_marginTop="10dp"
android:layout_marginStart="20dp"
android:layout_marginEnd="20dp"/>
</RelativeLayout>
</ScrollView>
That's the code for search Fragment

}
}
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

That's the code for fragment contains web view displaying search
#Override

webView = view.findViewById(R.id.webv);
PreviousB = view.findViewById(R.id.LQPButt);
NextB = view.findViewById(R.id.LQNButt);
q1 = "SELECT UrlLink FROM Interpretation_Books WHERE Book LIKE '%" + book_name + "%' AND Tasneef LIKE '%" + sura_name + "%' AND Bab_NoTashkeel LIKE '%" + aya_without_tashkeel + "%'";
c1 = myDB.rawQuery(q1, null);
if (c1 != null && c1.getCount() > 0) {
while (c1.moveToNext()) {
Url = c1.getString(0);
}
}
webView.loadUrl(Url);
