This feature isn’t available on every plan. Refer to your pricing plan to see if it’s included.

Select the index to personalize

Select a primary or replica. Advanced Personalization can’t personalize an index and its replicas at once. When you personalize a primary index, its and mappings apply to its replicas. The reverse is true too.

Select the attributes for affinities

Advanced Personalization needs to know which attributes to use as affinities. This lets it personalize the search experience. In the Affinities field, add the facet attributes to use. For example, say you run an ecommerce website. Its facet attributes might include category, color, gender, and size.

When selecting attributes as affinities, consider the following:
  • Advanced Personalization relies on facet attributes. In the Algolia dashboard, find the attributesForFaceting setting. Add the attributes you use as affinities to it.
  • It supports dot notation in facet attribute names. This helps when you select nested facet attributes as affinities.
  • It supports array attributes, so a single facet attribute can hold several values.
  • It doesn’t support the filterOnly modifier for facet attributes. Users won’t interact with these attributes. They’re used for filtering, not faceting.

Next step

After setting up the indices, define your event collection strategy. This improves the accuracy of user signals.
