Change Tabbed Page From Button

Hello,

I was currently working with Tabbed Page :

<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:me="clr-namespace:Let_s_go_out.Views.Pages;assembly=Let_s_go_out"
             x:Class="Let_s_go_out.Views.MainPage"
             >
  <TabbedPage.Children >
    <me:PlacesList />

    <me:PlaceSearch />


  </TabbedPage.Children>
</TabbedPage>

And in the PlaceSearch content I have a button :

<StackLayout Grid.Row="9" Orientation="Horizontal" > <Button Text="Rechercher" HorizontalOptions="Center" VerticalOptions="Center" Command="{Binding Search}"></Button> </StackLayout>

So my question is : How I can go on the "PlaceList" Tabbed page when the Button is clicked ?

Thanks
