Algolia Search & Discovery for Magento 2

The Algolia extension replaces the default search functionality in Magento Open Source and Adobe Commerce with a high-performance, typo-tolerant search experience. It leverages Algolia's infrastructure to provide:

• Autocompletion menu: An instant dropdown menu that provides access to the entire catalog regardless of category or attribute complexity.
• Instantsearch results page: Real-time updates for search results, navigation, and pagination after every keystroke.
• Recommend: Integration with Algolia Recommend to display features like "Frequently Bought Together" and "Related Products" on product detail pages.

The extension is built upon algoliasearch-client-php, autocomplete.js, and instantsearch.js.

The frontend delivers search configuration from the Magento server to client-side JavaScript libraries.

The Flow:

1. Admin settings are configured in system.xml.
2. ConfigHelper and specialized helpers read these settings.
3. Block/Configuration.php serializes this configuration into a JSON object.
4. This object is consumed by client-side libraries: autocomplete.js, instantsearch.js, insights.js, and recommend.js.
5. Search results are rendered entirely on the client-side (no server-side search results are returned by Magento).

Use this module if your store uses Magento's Multi-Source Inventory (MSI) and you need Algolia records to reflect aggregated stock status and per-source quantities.

Requirements:

• Base extension >=3.17.3
• For base extension >=3.19.0, use MSI module ^1.5.0.

Installation:

composer require algolia/algoliasearch-inventory-magento-2

This module routes product indexing through the Algolia Ingestion API. Use this if you require dashboard-managed JavaScript transformations, low-latency Collections support, or improved observability via Ingestion runs.

Requirements:

• PHP 8.3+
• Magento 2.4+
• Base extension ^3.19.0

Installation:

composer require algolia/algoliasearch-ingestion-magento-2

This module registers Algolia as a native Magento search engine backend, enabling server-side rendered (SSR) category and search-results pages. This is ideal for SEO and crawler readability. It can run alongside InstantSearch for hybrid setups.

Requirements:

• PHP 8.2+
• Magento 2.4+
• Base extension ^3.18
• For base extension >=3.19.0, use adapter module >=0.10.0.

Installation:

composer require algolia/algoliasearch-adapter-magento-2

The extension uses the Algolia PHP API Client for backend operations such as indexing, configuration, and search queries. The version of the PHP client used depends on your extension version:

• Indexing Customization
• Dispatched Backend Events

The recommended installation method is using Composer. To ensure you stay on a specific minor version while receiving automatic patch updates, use the tilde (~) operator in your composer.json file.

Example for version 3.19.x:

"algolia/algoliasearch-magento-2": "~3.19.0"

Full reindexing is an intentional, scheduled operation. Because full reindexing can be resource-intensive, it is disabled by default in the Magento indexer framework to prevent accidental triggers from third-party modules or ERP integrations.

To perform a full reindex, use the provided CLI commands. Commands are organized by concern, including Indexer/ (for per-entity or all-entity reindexing), Queue/, and Replica/.

The Algolia JavaScript libraries are compatible with standard Magento JavaScript bundling. If you use advanced bundling via the RequireJS optimizer, you must apply the Babel transpiler to the underlying source code.

Below is a sample .babelrc configuration for the transpiler:

{
    "presets": [
        [
            "@babel/preset-env",
            {
                "exclude": ["@babel/plugin-transform-template-literals"]
            }
        ],
        ["minify", { "builtIns": false, "mangle": false }]
    ],
    "comments": false
}
