Related content/related links

I wonder if i did not found any plugins or discussions to this topic.

Idea: if a write a blog entry or else i add some, "tags". When reading the blog entry it would be nice if the is a method to automatically show "related links" or "related content".

The easies way would be to extend the view of a single blog and display the search-listing-result for the matching tags from the blog.

I think it must me something like that

echo elgg_view('search/listing', [and something here but i don't know what *gg*]);




But i don't know the code to integrate. Can someone help me please?
