Glossary
Query Expansion
Query Expansion adds additional terms or meanings to a search query in a controlled manner, so that relevant products are not missed by word choice alone.
Purpose
Help customers when their language doesn’t exactly match product titles or catalog fields.
Risk
Too wide expansion can add irrelevant products and dilute strong exact matches.
Management
Use search data and regression tests to add expansion-oriented and reassess later.
