Exclude Pages from WordPress Search Results

To exclude pages from search results, add the following code to your functions.php file. You can also limit search to a specific Post Type by changing “post” on line 7 to the slug of the Post Type you want to display.

function filter_pages_from_search($query) {
    if ($query->is_search) {
        $query->set('post_type', 'post');
    }
    return $query;
}

add_filter('pre_get_posts','filter_pages_from_search');

Conversely, to make WordPress search pages as well as posts, use this code:

function filter_pages_from_search($query) {
    if ($query->is_search) {
        $query->set('post_type', array('post', 'page'));
    }
    return $query;
}

add_filter('pre_get_posts','filter_pages_from_search');
