Managing Multilingual WooCommerce Stores with Weaviate


Table of contents :


In today’s globalized world, businesses are expanding their reach beyond borders, catering to customers from different linguistic backgrounds. This has created a need for multilingual support in e-commerce platforms like WooCommerce. Managing a multilingual WooCommerce store can be a complex task, but with the help of powerful tools like Weaviate, it becomes much easier. Weaviate is an open-source knowledge graph that can be used to build intelligent applications. In this post, we will explore how to manage multilingual WooCommerce stores using Weaviate and provide some example code using the PHP client.


Managing Multilingual WooCommerce Stores with Weaviate

1. Setting up Weaviate:
The first step is to set up Weaviate on your server. You can follow the official documentation to install and configure Weaviate based on your operating system. Once Weaviate is up and running, you can proceed with the next steps.

2. Define the schema:
To manage multilingual data in Weaviate, you need to define a schema that supports multiple languages. For example, if you have a product entity, you can add properties like “name” and “description” in multiple languages. This allows you to store and retrieve data in different languages.

3. Importing data:
Next, you need to import your WooCommerce store data into Weaviate. This can be done using the Weaviate API or by writing a script that extracts data from your WooCommerce database and inserts it into Weaviate. For the purpose of this example, let’s assume you have a PHP script that retrieves product data from WooCommerce.

// Assuming you have already connected to your WooCommerce database

// Retrieve product data
$query = "SELECT * FROM wp_posts WHERE post_type = 'product'";
$result = mysqli_query($connection, $query);

// Iterate over the products
while ($row = mysqli_fetch_assoc($result)) {
 $product = [
 'name' => [
 'en' => $row['post_title'], // English name
 'fr' => $row['post_title_fr'], // French name
 // Add more language translations as needed
 'description' => [
 'en' => $row['post_content'], // English description
 'fr' => $row['post_content_fr'], // French description
 // Add more language translations as needed
// Add more properties as needed

// Send the product data to Weaviate API for indexing
$curl = curl_init('https://localhost:8080/v1/batch');
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode([$product]));
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);

// Close the database connection

In this code snippet, we retrieve the product data from the WooCommerce database and transform it into the desired multilingual format. Then, we make a POST request to the Weaviate API to index the products.


4. Searching for multilingual data:
Now that your data is stored in Weaviate, you can easily search for multilingual products. Weaviate provides powerful search capabilities that allow you to query data based on language-specific criteria. For example, you can search for products with a specific name in a particular language.

// Assuming you have already connected to Weaviate API

// Search for products with a specific name in English
$searchQuery = [
 'language' => 'en',
 'q' => 'blue shirt',
 'filters' => [
  'concept' =>
    'name' => 'Product',

$curl = curl_init('https://localhost:8080/v1/graphql');
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($searchQuery));
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
$response = curl_exec($curl);

// Process the search results
$results = json_decode($response, true);
// Handle the search results as needed

In this code snippet, we construct a search query to find products with the name “blue shirt” in English. The query is sent to the Weaviate GraphQL API, and the response is processed accordingly.


Multilingual Analyzers in Weaviate

When dealing with multilingual data in Weaviate, it is essential to consider how text analysis is performed on different languages. Weaviate provides a feature called multilingual analyzers, which allows you to configure specific analyzers for each language. This ensures that text processing, such as tokenization and stemming, is optimized for the characteristics of each language. Let’s explore how multilingual analyzers work in Weaviate.

1. Configuring Multilingual Analyzers:
Weaviate supports various analyzers for different languages, including built-in and custom analyzers. The first step is to define the analyzers in the Weaviate schema. Each analyzer is associated with a specific language. For example, you can define an analyzer for English, another for French, and so on.

2. Tokenization and Stemming:
Tokenization is the process of breaking text into individual units, such as words or phrases. Stemming, on the other hand, reduces words to their base or root form. These processes are language-specific, and using the appropriate analyzer ensures accurate tokenization and stemming for each language.

3. Language-specific Stopwords:
Stopwords are common words like “and,” “the,” or “is” that are often removed during text analysis. However, stopwords vary across languages. For instance, the word “the” might be a common stopword in English, but it may have different counterparts in other languages. By using multilingual analyzers, you can handle language-specific stopwords effectively.

4. Example Configuration:
Let’s assume you want to configure Weaviate with multilingual analyzers for English and French. Here’s an example configuration in the Weaviate schema:

 "classes": [
  "class": "Product",
  "properties": [
     "name": "name",
     "dataType": ["text"],
     "indexInverted": true,
     "fullText": true,
     "multilingual": {
      "analyzers": {
       "en": "standard",
       "fr": "french"
     "stopwords": {
      "en": ["the", "and", "is"],
      "fr": ["le", "et", "est"]

In this example, the “name” property of the “Product” class is configured as multilingual. The “en” analyzer uses the standard analyzer, while the “fr” analyzer uses the French-specific analyzer. Language-specific stopwords are also defined.
