What should I do if the DEDECMS related documents are not relevant?

DEDE related articles are completely irrelevant. I have friends in DEDE The official release of related articles based on TAG is also very good. Unfortunately, after I change the DEDE code based on the article there, it always fails. It may be due to limited ability, of course, there may also be a problem with the code

1. Add

　//查询指定栏目里包含相应关键字的文章，并列出
　　
　　//参数说明：$showImg 是否显示缩略图，0表示不显示，1表示显示
　　
　　// $titleLen 标题长度，0表示无限
　　
　　// $rowCount 输出行数，0表示无限
　　
　　// $typeid 栏目ID，0表示所有栏目
　　
　　// $keyWord 关键字，字符串
　　
　　function ShowKeyWordArc($showImg,$titleLen,$rowCount,$typeid,$keyWord){
　　
　　$dsql = new DedeSql(false);
　　
　　$sql = TypeGetSunID($typeid,$dsql);
　　
　　//关键字分词技术
　　
　　$ks = explode(" ",$keyWord);
　　
　　foreach($ks as $k){
　　
　　$k = trim($k);
　　
　　if ($k!="") {
　　
　　$kwsqlarr[] = " (dede_archives.title like &#39;%$k%&#39;) ";
　　
　　//$kwsqlarr[] = " (dede_archives.keywords like &#39;%$k%&#39;) "; //如果需要相关到其它文章的关键字，解除此行注释
　　
　　}
　　
　　}
　　
　　$where = implode(&#39; OR &#39;,$kwsqlarr);
　　
　　$sql="Select tp.namerule,tp.typedir,dede_full_search.aid,dede_full_search.url,dede_archives.* From dede_full_search left join dede_archives on dede_full_search.aid=dede_archives.ID left join dede_arctype tp on dede_archives.typeid=tp.ID where {$sql} and ((dede_archives.title like &#39;%".$keyWord."%&#39;) or $where) order by dede_full_search.aid desc";
