Maintain relevance when catalogue and variants grow.
A large catalogue requires more than fast infrastructure. Taxonomy, attributes, index strategy and evaluation determine whether customers continue to find the right product.
Product versus variant
Determine whether search returns at product, variant or item level and how duplication is prevented.
Manage facets
Show filters that are relevant within the current query and avoid hundreds of barely used attributes.
Index strategy
Combine complete synchronization with incremental updates for price, inventory and product changes.
Query segments
SKU-Search, technical combinations and broad category questions require different ranking logic.
Performance
Measure latency under realistic filter combinations, peak load and large result sets.
Evaluation
Use a representative query set and regression tests for each relevant change.
Manageability
Automate where possible, but keep exceptions, rules and responsibilities transparent.
