  title: OpenSearch for product search
  status: proposed
  date: 2026-10-19
  elements: [api, worker, db]
  diagrams: [0200-containers/online-shop.archify]
context: >
  Catalogue search runs as SQL LIKE queries on the
  database. Typos find nothing and the catalogue page is
  the slowest page in the shop.
decision: >
  Add a dedicated search service on OpenSearch. The API
  queries it; the worker rebuilds the index from the
  database after every catalogue change.
consequences: >
  The index is derived data under decision 0001 and may be
  rebuilt at any time. One more service to run. Search
  results can lag the database by the rebuild interval.
