Magento Inventory (MSI)

The code for the Algolia_AlgoliaSearchInventory module is a community-developed module available on GitHub. Though Algolia is a contributor to this repository, there is no product roadmap for this module and it’s not aligned with the Algolia/Magento integration product releases.
The Algolia extension supports the Magento Inventory module, also known as Multi-Source Inventory (MSI). For more information, see Inventory Management in the Magento developer documentation. The MSI features include:
  • Different configurations for merchants whose inventory originates from single or multiple sources
  • Stock tracking through assigned sources
  • Concurrent checkout protection
  • Shipment matching algorithms
As a consequence, you can create multiple inventory sources and stocks to manage the availability of products in your stores.

​
Compatibility

MSI changed the way a product is determined to be in stock or not. To support the new behavior and to keep backwards compatibility with older versions of the Magento 2 integration, Algolia provides an optional module, Algolia_AlgoliaSearchInventory. You can download this module separately with Composer and use it in addition to the Algolia extension. You can use the Algolia_AlgoliaSearchInventory module with version 1.12 or later of the Algolia extension. To decide which version of the Algolia_AlgoliaSearchInventory you need to install, check the compatibility on GitHub.

​
Requirements

You can use Algolia_AlgoliaSearchInventory if:
  • You’re using Magento version 2.3 or later
  • You’re using multiple sources/stocks to manage your inventory
If you don’t use MSI, adding the Algolia_AlgoliaSearchInventory module won’t break your indexing process, but it may slow it down. You should only install the module if you’re using MSI.

​
Install the Algolia_AlgoliaSearchInventory module

composer require algolia/algoliasearch-inventory-magento-2
php bin/magento module:enable Algolia_AlgoliaSearchInventory
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy # in case you're on production mode
Now, your multiple sources and stocks are handled as you expect and you can continue to use the Algolia extension.

​
Backend search adapter

The Algolia_SearchAdapter module is an official companion module available on GitHub. It’s maintained by Algolia and aligned with the Algolia/Magento integration product releases starting with version 3.18.
The Algolia Search Adapter registers Algolia as a native Magento 2 search engine and provides backend (server-side) rendering for category pages and search results. When enabled, Magento’s standard product listing blocks query Algolia directly making content visible to search-engine crawlers, LLM-based discovery tools, and any client that doesn’t run JavaScript.

​
Install the Algolia_SearchAdapter module

composer require algolia/algoliasearch-adapter-magento-2
php bin/magento module:enable Algolia_SearchAdapter
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:flush
