With this plugin you can define search keywords that redirect to specified URLs. Some example of usage:
<ol>
<li>Optimizing search to get users to desired content fast.</li>
<li>Marketing with search keywords. Much easier for user to remember “search free stuff” than expecting a user to remember/type a URL.</li>
<li>Search keyword easter-eggs. Search “guacamole” -> http://mysite.com/awesome-guac-recipe.</li>
<li>Fun!</li>
</ol>
