Why is this called a plugin? As far as I can see it's just an additonal search term (hn).

http://duckduckgo.com/?q=hn+startup+ideas

Compare with DDG's existing bang code for HN: !hn + startup + ideas

That searches hnsearch.com directly, and gives good results on hnsearch for the search terms.

The "plugin" search from the post has an hnsearch box at the top of DDG's results page, but when you follow the hnsearch link, those results are not as good as the !hn search (IMO).

The nice thing about the "plugin" search is that there are results from the rest of the web. But that's normal.

Am I missing something?
