When there is only one search result available for a query, automatically redirect the user to that result.
This will work with any theme and any posts, pages, or custom post types that would be shown in search results.
<h3>Available Filters</h3>
You can filter <code>one_search_result_pre_check</code> to false if you need to short-circuit and disable the redirect dynamically.
You can modify the redirect code with <code>once_search_result_redirect_code</code>, defaults to 302.

One Search Result

Automatically send a user to the page or post if it's the only search result available.

WP Ajax Search Widget is a replacement for the standard search widget but instead of redirecting you to a new search page the results are returned underneath the search input with an option to click through to the standard results page.
The widget allows you to choose how many results to show.
