For some reason when i listed the comments under posts on this site, i used the search function and then searched for the related uid, which maybe was easier at the time than adding an additional category to search.

When I did this it also recorded the uid in the search results which is annoying. 

Now i need to change the list order on the comments and i cant as it will effect search so i need to redo it now anyway. So i should have just added an additional list type in the first place.

Current Search Code

PHP

if($comments_view_enabled) {
    /* rather than doing a search here it should be doing a comment list  */
    $comments_list = $comments->list_all(
            $start = 0,
            $max = 200,
            $list_type = "search",
            $template_file = "related_discussions-full-list-item.html",
            $search_term = $class->uid
        );
        //$template->set("related_discussions",$related_discussions);
        $page_content .= $comments_list;
}

Added a custom list, not sure why i didnt just do this, as its quite easy. 

PHP

if($list_type == "comments") {
        $sql = "select * from $db_table_name where linked_uid = '$search_term' order by insdate asc limit $start,$max";
}  

then just changed the listing type to comments rather than search

PHP

if($comments_view_enabled) {
    $comments_list = $comments->list_all(
            $start = 0,
            $max = 200,
            $list_type = "comments",
            $template_file = "related_discussions-full-list-item.html",
            $search_term = $class->uid
        );
        $page_content .= $comments_list;
}
