The advantages of server-side faceted search for large WordPress and WooCommerce stores


Table of contents :


Faceted search is a powerful feature that allows users to quickly narrow down their search results by selecting various filters or categories. This is particularly useful for large WordPress and WooCommerce stores with a vast amount of products, as it helps users find what they’re looking for more efficiently. While there are different approaches to implementing faceted search, server-side faceted search has distinct advantages for these types of stores. In this post, we’ll explore the benefits of server-side faceted search, provide some PHP and JavaScript code examples, and discuss how WPSOLR can help improve your search functionality.

Advantages of Server-Side Faceted Search

1. Faster Performance: Server-side faceted search performs the filtering and aggregation on the server before sending the results to the client. This reduces the amount of data transferred and processed on the client-side, resulting in faster search performance, especially for large stores with thousands or millions of products.

2. Scalability: Server-side faceted search offloads the computation to the server, allowing for better scalability. As your store grows and the number of products increases, server-side faceted search can efficiently handle the increasing load without impacting the user experience.

3. Security: By handling the search and filtering logic on the server-side, sensitive information can be kept secure. User authentication and authorization can be applied more easily, ensuring that only authorized users can access certain facets or categories.

4. Enhanced User Experience: Server-side faceted search provides a smoother user experience by reducing the time it takes to load search results and apply filters. Users can quickly refine their search based on various attributes like price, brand, size, color, and more, resulting in a more personalized and efficient search process.

PHP and JavaScript Code Examples

Here’s an example of server-side faceted search implementation using PHP on the server-side and JavaScript on the client-side:

// PHP server-side code for faceted search
$products = get_products(); // Fetch products from the database
$filters = get_search_filters(); // Fetch available filters from the database

// Apply selected filters
$filteredProducts = apply_filters($products, $selectedFilters);

// Return filtered products to the client
echo json_encode($filteredProducts);

// JavaScript client-side code for faceted search
function applyFilters(selectedFilters) {
  // Send selected filters to the server
  fetch('/apply-filters', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    body: JSON.stringify(selectedFilters),
  .then((response) => response.json())
  .then((filteredProducts) => {
    // Update search results on the client-side
