A retailer wants shoppers to photograph an item and be shown matching SKUs from a 50,000-item catalog using the Vision API's product search feature. Which option lists the setup steps in the correct order?
Show answer and explanation
Answer: B
Product Search groups items in a product set, and each product holds one or more reference images. The product set is created first, then products are created with their reference images, each product is added to the set, and image queries are run against the populated set. The service builds its search index as products are imported, so no separate index-building call is needed. Querying an empty or incomplete set returns no useful matches.
Why the other options are wrong
- A. Querying happens last, after a product set exists and is populated. A product also cannot hold reference images before it is created, so this order is reversed at nearly every step.
- C. Adding products before the set exists, and querying before any items are loaded, leaves the search with nothing to match against. Reference images should be attached before products join the set.
- D. A photo cannot be meaningfully queried until the set contains products. Creating the product after the query and setting the set last breaks the dependency chain the service relies on.
