Include "Pages" in Search – with code

Hi,

I am trying to include “pages” and “posts” in the search results. However, I am not using the widget or tag, as I’m adding the search bar into the code using…

<?php Multisite_Global_Search::ms_global_search_horizontal_form('globalsearch') ?>

So, how do I include searching for “pages” (from the main site and all of the other subsites) into the above code?

Thank you.
