Save your visitors from unhelpful 404 errors!
Instead of quickly giving up when a visitor reaches content that doesn’t exist, make an effort to guess what they were 
after in the first place. This plugin will perform a search of your posts, pages, tags and categories, using keywords from the requested 
URL. If there’s a match, redirect to that content instead of showing the error. If there’s more than one match, the 
404 template can use some template tags to provide a list of suggestions to the visitor.
See the <a href="http://michael.tyson.id.au/smart-404" rel="nofollow ugc">Smart 404 homepage</a> for more information.
<h3>Template tags</h3>
<code>smart404_has_suggestions</code>
Returns true if there are some suggestions, false otherwise
<code>smart404_get_suggestions</code>
Retrieve an array of post objects for rendering manually.
<code>smart404_suggestions</code>
Draw a list of suggested posts.
Pass the parameter “list” to render suggestions as a list.
<code>smart404_loop</code>
Query posts for use in a Loop. Eg:
<pre><code><?php smart404_loop(); ?>
<?php while (have_posts()) : the_post(); ?>
 <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
 <?php the_excerpt(); ?>
<?php endwhile; ?>
</code></pre>
Note that the loop will not display pages correctly, as it is not built to support them. It is recommended that if you use 
a loop like that above, do not enable searching of pages.
<code>smart404_get_search_terms</code>
Retrieve an array of search terms used to populate the suggestions list, for use with contextual highlighting, etc.
