Super fast WP Search Suggest

In ‘/wp-content/’ folder create another folder: ‘mu-plugins’ (if does’n exists; ‘mu’ – must use).

In ‘/wp-content/mu-plugins/’ create file, ex.:

disable_plugins_when_wp_search_suggest.php

Add code into ‘disable_plugins_when_wp_search_suggest.php’:

<?php
    if ( ! function_exists('disable_plugins_when_wp_search_suggest') ) {
        add_filter( 'option_active_plugins', 'disable_plugins_when_wp_search_suggest' );
        function disable_plugins_when_wp_search_suggest( $active_plugins ) {
            $uri = 'action=wp-search-suggest';
            if ( false !== strpos( $_SERVER['REQUEST_URI'], $uri) ) {
                $for_enable = 'wp-search-suggest/wp-search-suggest.php'; 
                $index = array_search($for_enable, $active_plugins);
                foreach( $active_plugins as $idx => $plugin ) {
                    if ( $index !== array_search( $plugin, $active_plugins) ) {
                        unset($active_plugins[$idx]);
                    }
                }
            }
            return $active_plugins;
        }
    }
?>

Now all active plugins will not be loaded during the search except WP Search Suggest and server response time will be reduced by several times (from 1.5 seconds to 200 milliseconds with 30 active plugins for me).
