Managing multilingual WooCommerce stores can be a complex task, especially when it comes to ensuring a seamless search experience for customers across different languages. However, with the power of Google Retail Search and the flexibility of the WooCommerce platform, you can effectively manage multilingual stores and provide a consistent search experience to your customers. In this post, we will explore how you can leverage the Google Retail Search API to enhance search functionality in your multilingual WooCommerce store and provide relevant search results to users in their preferred language.


Google Retail Search API

The Google Retail Search API is a powerful tool that allows you to integrate Google’s search technology into your online store. By utilizing this API, you can enhance the search functionality of your WooCommerce store by leveraging Google’s sophisticated search algorithms and language capabilities. The API provides features such as autocomplete suggestions, search query corrections, and search filters, which can greatly improve the user experience and help customers find the products they are looking for.


Managing Multilingual Stores

When managing a multilingual WooCommerce store, it is crucial to ensure that the search functionality is language-aware. This means that the search results should be relevant and accurate for users searching in different languages. To achieve this, you can utilize the Google Retail Search API’s language features.

First, you need to determine the language preferences of your users. This can be done by detecting the user’s browser language or allowing them to manually select their preferred language. Once you have the user’s language preference, you can pass it as a parameter to the Google Retail Search API when making search requests.

Here is an example code snippet in PHP using the Google Retail Search API:

require 'vendor/autoload.php';

use Google\Cloud\Retail\V2\SearchServiceClient;
use Google\Cloud\Retail\V2\SearchRequest\Filter;
use Google\Protobuf\Struct;

function searchProducts($language, $query)
 $searchServiceClient = new SearchServiceClient();

 $placement = 'projects/your-project-id/locations/global/catalogs/default_catalog/placements/default_search';

 $query = 'language_code:' . $language . ' ' . $query;

 $searchRequest = new \Google\Cloud\Retail\V2\SearchRequest();

 $response = $searchServiceClient->search($searchRequest);

 return $response;

// Example usage:
$language = 'en'; // User's language preference
$query = 'red shoes'; // User's search query

$response = searchProducts($language, $query);

// Process and display the search results
// ...

In the example code above, we initialize the SearchServiceClient and set the placement to define where the search should be performed within your store. We then construct the search query by appending the language code and the user’s search query. Finally, we make the search request using the SearchRequest object and retrieve the response, which contains the search results.
