How can I make search results only show posts not pages?

In case anyone else needs this...

I just did a quick google search and found this PHP code which seems to have worked:

//Exclude pages from WordPress Search
if (!is_admin()) {
function wpb_search_filter($query) {
if ($query->is_search) {
$query->set('post_type', 'post');
}
return $query;
}
add_filter('pre_get_posts','wpb_search_filter');
}

Glad to see you found the answer - and thanks for sharing.
