In this lesson

index Shop products and query them. Prepares MID-043-LAB1.

Draft outline details

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

Why define mappings explicitly?

Show answer

Dynamic mapping guesses types and often guesses wrong.

Apply this lesson with the module's lab, exercises and quiz.
