عرض عملي: بحث المنتجات مع تحمّل الأخطاء الإملائية والأوجه

خطوة بخطوة

1. Start OpenSearch (single node) with Docker; verify image version before recording.
2. Create an index products_v1 with explicit mappings (name text, category keyword, price scaled/double) and alias products.
3. Bulk-load products from the catalog database and run runing shoes with fuzziness; show results.
4. Add category and price-range facets from aggregations.
5. Planned mistake: rely on dynamic mapping, so category is analyzed as text and the facet shows broken words. Fix: explicit mapping with keyword, reindex.
6. Apply an indexer consumer for ProductUpdated and show an update appearing in search.
