Kau-Boy’s AutoCompleter is deprecated and will be removed from the plugin directory on June 19, 2023, 14 years after its first release. Thanks to everyone who used the plugin, gave constructive feedback, rated it and send me messages on how it helped them with their sites. This was <a href="https://kau-boys.de/19/allgemein/mein-erster-blog" rel="nofollow ugc">my very first WordPress plugin, and it started my journey into the WordPress community</a>. If you see this message, you are one of few, who still have this plugin installed. But now feel free to remove it from your site. If you still want an auto-completion/suggestion, try out <a href="https://wordpress.org/plugins/wp-search-suggest/" rel="ugc">WP Search Suggest</a>, which is still actively maintained. You can find my other plugins <a href="https://profiles.wordpress.org/kau-boy/#content-plugins" rel="nofollow ugc">on my WordPress profile page</a>.
As you can choose between Prototype and jQuery, you can just take the framework you prefer or use the most. You can also set your own sytles without losing these settings in case the plugin is updated. 
The results are shown right under the search field. The search string is highlighted in the title and/or the content. You can also cutomize the ID of the search field and the number of choices.
