Learn about how often we index and sync products data

We run new and existing product updates in near real-time.

The following settings are applied only on re-index:

  • Synonyms

  • Searchable fields + priorities

  • Indexed fields

  • Data extractors

  • Out-of-stock/exclude behavior

  • Changes to Autocomplete keywords

All other settings and changes to product data are applied in near real-time. Please note that there is still usually a delay of several seconds to several minutes until the change takes effect due to how the data flows work.

We run a full catalog re-index every 6 hours with this schedule:

Sync start (UTC time)

Approx sync finish (UTC time)


03:00 - 04:00


09:00 - 10:00


15:00 - 16:00


21:00 - 22:00

How does data sync work in practice?

  • Once Nosto’s Search and Category Merchandising 2.0 modules are enabled, they will receive product data from Nosto platform in up to 6 or 12 hours: during the next catalog or the second reindex (see schedule above).

  • When you change searchable fields, indexed fields and synonyms, it will reflect in Nosto’s Search during the next catalog reindex (see schedule above).

  • When you add new products or update existing product's data (e.g. price, availability etc) in your store's platform, it will be reflected in Nosto platform and Nosto’s Search in near real-time, usually up to a few minutes, very rarely with 5-10 minutes delay.

  • When changing the exclusion logic (e.g. removing exclusion for certain products), it will reflect in Nosto’s Search during the next catalog reindex (see schedule above). Excluded products are not indexed.

  • All other changes made in the backend (merchandising rules, out-of-stock behaviour etc) will take action in real time.
