How to implement autocomplete search with Algolia in WooCommerce

Table of Contents


Implementing an autocomplete search feature in WooCommerce can greatly enhance the user experience and make it easier for customers to find the products they are looking for. Algolia is a powerful search platform that specializes in providing fast and relevant search results, and integrating it into your WooCommerce store can significantly improve the search functionality. In this post, we will discuss how to implement autocomplete search with Algolia in WooCommerce.

Step 1: Setting up Algolia Account and Indexing:

The first step is to create an Algolia account and set up an index for your WooCommerce products. Once you have created an account, you will need to install the Algolia plugin for WooCommerce. This plugin will facilitate the integration between WooCommerce and Algolia by providing the necessary functionalities to synchronize your products with Algolia’s index.

Step 2: Configuring the Algolia plugin:

After installing and activating the Algolia plugin, you will need to provide your Algolia API credentials in the plugin settings. You can obtain these credentials from your Algolia account dashboard. Once you have entered the API credentials, you can configure the indexing settings according to your requirements. For example, you can choose which product attributes to include in the search index, enable/disable typo tolerance, or configure sorting preferences.

Step 3: Implementing Autocomplete Search:

To enable autocomplete search in WooCommerce, we will need to modify the search form and add some JavaScript functionality. First, we will need to modify the WooCommerce search form to include the necessary markup and JavaScript code.

function autocomplete_search_form() {
<form class="search-form" role="search" action="<?php echo esc_url( home_url( '/' ) ); ?>" method="get"><label>
<input class="search-field" title="<?php echo esc_attr_x( 'Search for:', 'label', 'woocommerce' ); ?>" name="s" type="search" value="<?php echo get_search_query(); ?>" placeholder="<?php echo esc_attr_x( 'Search products...', 'placeholder', 'woocommerce' ); ?>" />
<input name="post_type" type="hidden" value="product" />
<button class="search-button" type="submit">
return ob_get_clean();
add_shortcode( 'autocomplete_search_form', 'autocomplete_search_form' );

The code above adds a new shortcode ‘[autocomplete_search_form]’ which can be used to display the modified search form in any part of your WooCommerce store.

Next, we will need to add the JavaScript code that communicates with the Algolia search service to provide autocomplete suggestions. The Algolia JavaScript client library provides all the necessary methods to interact with the search index.

function algolia_autocomplete_search_scripts() {
    wp_enqueue_script( 'algoliasearch', '', array(), '4.10.1', true );
    wp_enqueue_script( 'autocomplete_search', get_template_directory_uri() . '/js/autocomplete_search.js', array( 'jquery' ), '1.0.0', true );

    wp_localize_script( 'autocomplete_search', 'autocomplete_search_params', array(
        'index_name' => get_option( 'algolia_autocomplete_index', 'products' ),
        'app_id' => get_option( 'algolia_application_id' ),
        'api_key' => get_option( 'algolia_search_api_key' ),
    ) );
add_action( 'wp_enqueue_scripts', 'algolia_autocomplete_search_scripts' );

The above code registers and enqueues the necessary JavaScript files for Algolia and the autocomplete search functionality. It also passes the necessary parameters, such as the index name and the Algolia API credentials, to the JavaScript file that handles the autocomplete search.

The ‘autocomplete_search.js’ file would contain the actual JavaScript code to implement the autocomplete search functionality using Algolia’s JavaScript client library. This code would listen for user input, make AJAX requests to the Algolia search API, and display the search suggestions in the autocomplete dropdown.


Implementing autocomplete search with Algolia in WooCommerce can greatly improve the search experience for your customers. By leveraging Algolia’s powerful search capabilities, you can provide fast and relevant search suggestions in real-time. By following the steps outlined above and using the provided PHP and JavaScript code snippets, you can easily implement autocomplete search in your WooCommerce store.
