Introduction to Shopify Indexing

To index your data, the extension calls the Shopify API and uses Shopify webhooks.

Full reindexing

When you install the app in your store, the extension automatically starts indexing your data.

This is called a full reindex. You can trigger a full reindex, for any data type, in the Indexing tab.

Automatic updates

The app is designed to automatically keep your data up to date. It uses Shopify webhooks to know when you make updates to your Shopify catalog and to immediately push the changes.

Blog posts and pages are a special case. Shopify doesn’t provide webhooks for them. To keep your search up to date, the app does a full reindex of the articles and pages every day. If you want your search results updated faster, you can trigger a full reindexing from your Indexing tab.

Indexing jobs

To index your data while keeping your data consistent and respecting Shopify’s rate limiting, the extension uses an indexing queue: all your indexing jobs wait until they can be processed. You can see the number of queued indexing jobs in the Indexing tab of the application.

Whenever you notice that your data isn’t up to date, you should check the indexing queue. Every data packet that is either waiting to be or is actively being processed is listed here, alongside a progress bar.

Algolia operations

When automatic updates are enabled, the app generates various Algolia indexing operations to keep your data in sync. Here’s how many indexing operations the app generates based on the update type received from Shopify:

  • Product updates
    The number of indexing operations for each product is equal to the number of variants for that product.
    For example, if you update 5 products with 4 variants each, the total number of indexing operations is 20 (5 times 4).
  • Collection updates
    If you enable collection indexing, the number of indexing operations for each collection is equal to the number of product variants in that collection (if you enable the “Collection Pages” feature or “Enable faceting on collections” option), plus one operation for the collection itself.
    For example, if you didn’t enable the “Collection Pages” feature and update 2 collections that have 20 and 30 variants respectively, there are only 2 indexing operation to index the collections themselves.
    However, if you did enable the “Collection Pages” feature, the number of indexing operations will be 52: 2 for updating the collections themselves, and 50 for updating their variants.
  • Order updates
    Each order update generates 1 indexing operation. For example, if the app received 20 order updates, it will generate 20 indexing operations.

When performing a full reindex, similar numbers apply:

  • Full product reindex
    The number of indexing operations generated is equal to the total number of published variants in the store.
  • Full collection reindex
    The number of indexing operations is equal to the total number of published collections. If you enable the “Collection Pages” feature or the “Enable faceting on collections” option, the app makes extra indexing operations equal to the number of variants in those collections.
