Better WP Search improves the default WordPress search functionality currently in two ways:
<ol>
<li>If there is only one search result, redirect to that post; and</li>
<li>Replaces search URL from /?s=query to /search/query.</li>
</ol>
The plugin will offer more features in the future. If you have a suggestion? Use the plugin’s 
forum to make suggestions.
