Wiki Style Search will cause WP’s search to go directly to a page or post if a page or post’s title matches the search query; otherwise search results will display as usual. Plugin makes search function similar to that of Wikipedia.
For Example:
<ul>
<li>A search query of ‘spider’: http://thelargest.net/?s=spider takes you to http://thelargest.net/spider</li>
<li>A search query of ‘cruise ship’: http://thelargest.net/?s=cruise+ship takes you to http://thelargest.net/cruise-ship</li>
</ul>
Test more at <a href="http://thelargest.net" rel="nofollow ugc">The Largest</a>.

Wiki Style Search

Wiki Style Search bypasses search results and directs users directly to an article if an article name matches their query.

The basic idea here is that you can easily link to the wikipedia entry for a given topic by putting the [wikipedia]topic[/wikipedia] tag into your post. The tag is replaced by a link that executes the wikipedia search form for that topic.
The plan is to augment this with a mouseover popup containing an excerpt from the wikipedia page.

Wp-Wikipedia-Excerpt

This plugin replaces [wikipedia]topic[/wikipedia] with a wikipedia search link for that term.
