Toolbar is in front

Try to add your toolbar inside the scrollView, so it will also go up when you scroll:

      <LinearLayout

          xmlns:app="http://schemas.android.com/apk/res-auto"

        app:contentScrim="@color/colorPrimary"
        app:expandedTitleTextAppearance="@style/TransparentText"
        app:layout_scrollFlags="scroll|enterAlways|snap">

       <android.support.v7.widget.Toolbar
            android:id="@+id/toolbarSearch"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/defaultColorBackground"

            app:theme="@style/ThemeOverlay.AppCompat.Light"/>
</android.support.design.widget.CollapsingToolbarLayout>

With this code you will make your Toolbar roll obeying all the content. Remembering that the ScrollView should contain the:

<app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
