The Three Configuration Surfaces
Algorithm
The ranking layer. One or more named algorithms scoped to specific searches or categories, each with five configuration tabs covering relevance (including the search engine choice), performance, personalization, newness, and ranking behavior.
Field Settings
The per-field configuration layer. For each indexed field, you define its type, how it participates in search and faceting, how Experro’s natural language processing layer treats it, and whether it carries internal-only data.
Catalog Settings
The catalog-wide configuration layer. Settings that apply across every product, including Gen AI vector indexing, the field used for precision and personalization, out-of-stock handling, color grouping, and variant slicing attributes.
How They Relate
The three surfaces build on one another, from shaping the raw data to ranking the final results:- Field Settings shapes the data — it defines what each field is and how it can be used.
- Catalog Settings tunes catalog-wide behavior on top of that data.
- Algorithm decides how the resulting indexed catalog is ranked for any given query.
Changes to Field Settings or to certain Catalog Settings options require a catalog re-index before they take effect. Algorithm changes apply immediately on save and activate.
