Use different archive template for plugin

Question

In my blog, I'm using a plugin for an encyclopedia. Unfortunately, the plugin uses the archive template from my blog.

How can I use a different page / template for the encyclopedia? Here is the function of the plugin: (From the plugin-author I didn't get any support).

function Define_Rewrite_Rules(){
$post_type = Get_Post_Type_Object($this->post_type);
$archive_url_path = $post_type->rewrite['slug'];
$this->rewrite_rules[SPrintF('%s/filter:([^/]+)/?$', $archive_url_path)] = SPrintF('index.php?post_type=%s&filter=$matches[1]', $this->post_type);
$this->rewrite_rules[SPrintF('%s/filter:([^/]+)/page/([0-9]{1,})/?$', $archive_url_path)] = SPrintF('index.php?post_type=%s&filter=$matches[1]&paged=$matches[2]', $this->post_type);
}

Create a new template in your theme named archive-encyclopedia.php.

In your theme folder, copy the archive.php or index.php and name it archive-encyclopedia.php. Now you can make your custom changes to the new template.

This template will be called instead of the default archive template as archive-{post-type}.php will be used before archive.php or index.php.
