Hi,
if the pages are categorized in any way, then you can use any of the inclusion/exclusion options.
Otherwise you can try using a custom code to exclude them via post-process. Try adding this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!
add_filter( 'asp_results', 'asp_filter_posts_by_url', 10, 1 );
function asp_filter_posts_by_url( $results ) {
foreach ($results as $k => &$r ) {
if ( strpos($r->link, '/book-accomodation') === false )
unset($results[$k]);
}
return $results;
}
