Your build is green and your shop’s search is broken: NDCG as a CI gate in .NET

A shopkeeper looks at two trays on his counter: an empty one beside an order for women's running shoes, and a full one with running shoes graded 3, a t-shirt graded 1 and a backpack graded 0, under a blackboard that reads NDCG@10, never below 0.80.

Test ecommerce search like code: an NDCG@10 gate in CI for .NET and Elasticsearch, and the bug it found on its first run.
