I discovered Jump to post link in search results didn't have pretty urls, so i fixed in your extenstion with this line : $tpl_ary['U_VIEW_POST'] = $tpl_ary['U_VIEW_TOPIC'].'#p'.$event['row']['post_id'];
Added to function search_modify_tpl_ary, under $event['tpl_ary'] = $tpl_ary;
And it's works, have pretty url same like topic but added post_id param on the end
