List of links to related articles (by keyword)

templates/content/datatype/view/ezkeyword.tpl from a recent project:

<p>{"Keywords used in this article:"|i18n("design/mydesign/keywords")}</p>
{def $keyword_array = $attribute.content.keyword_string|explode(',')
     $keyword_count = 0
     $keyword_string = ''}
{foreach $keyword_array as $keyword}
    {set $keyword_string = $keyword|trim()}
    {set $keyword_count = fetch( 'content', 'keyword_count', hash( 'alphabet', $keyword_string ) )}
    {if $keyword_count|gt( 1 )}
        <a href={concat('content/keyword/', $keyword_string)|ezurl}>{$keyword_string|wash}</a>
    {else}
        <span>{$keyword_string|wash}</span>
    {/if}
{/foreach}
{undef}

With this you can easily set limit using max parameter on foreach, and you can also add classid in url as parameter if you want to filter on that.

But look like you want to link directly to the articles that use same keyword, so you should probably look at:
