This plugin lets you provide the user with search suggestions based on the information entered in the search field.
It adds an AJAX call to the search form, returning matches for the current search query from the database. 
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.

WP Search Suggest

С плагином интернет-магазина WP Shop работает отлично.

Чтобы саджест-поиск не искал в ненужных типах записей в файл functions.php достаточно включить функцию-фильтр, в которой настроить WP Search Suggest под себя:


    `/*
    * Customize plugin WP Search Suggest
    */
    function wp_search_suggest_custom($query_args) {

        $query_args += [
            'post_type' => ['post', 'page'],
            'posts_per_page' => 10,
        ];

        return $query_args;
    }
    add_filter( 'wpss_search_query_args', 'wp_search_suggest_custom');`

Отличный плагин для поиска по товарам с подсказками

I like this simple Plugin, I only would wish to have more results or to set an option for this ;)

Simple is the Best!

Great and clean plugin!

Provides title suggestions while typing a search query, using the built-in jQuery suggest script.

This plugin uses an abstraction of jQueryUI’s autocomplete widget that interacts with the unofficial/undocumented Google Suggest API. 
Props go to Haochi Chen.
It adds an AJAX call to the search form, returning matches for the current search query. 
Make sure the searchform input field has <code>id="s"</code> applied, so this plugin can hook in the existing WordPress API to unfold its magic.
