Vertex AI Search: Search Tunning with Structured Data

Hello everyone,

I’m working with a Vertex AI Search app where the data store source is a BigQuery table. This means my search engine uses a structured data store with product information. My current problem is getting my app to provide company-specific results. I’ve tried boosting some products, but this isn’t a scalable solution. Because of this, I want to try search tuning. I know the official documentation says that search tuning can “only be applied to unstructured data stores.” However, while doing some experiments with my app, I was able to upload a mini tuning dataset.

Has anyone had any experience with this? Do you have any recommendations for this use case? I’m hoping to hear from anyone who has found a way to apply search tuning to structured data or has an alternative solution.

Here’s a sample of one of my products. I gave each product an “expanded description” to help the engine with semantic context:

{
“brand”: “GENERIC”,
“sales_unit”: {
“content_quantity”: 1,
“content_unit_name”: “unit”,
“content_measure_unit”: “units”,
“packaging_type”: “unit”,
“packaging_quantity”: 1
},
“genai_description”: “The Christmas Organization Boxes S012-000028 are the ideal solution for the efficient storage of festive decorations, ornaments, and accessories after the holiday season. Designed to protect and keep your most precious items in perfect condition, these generic boxes offer optimized storage space, preventing clutter and facilitating the next setup. Their practical design allows for easy stacking, maximizing storage space in storage rooms, closets, or garages, and extending the lifespan of your decorations year after year. These boxes are essential for maintaining order and organization in your home, ensuring that every ornament is ready to celebrate future Christmases.”,
“sku”: “S012-000028”,
“name”: “CHRISTMAS ORGANIZATION BOXES”,
“genai_labels”: “organization boxes, Christmas storage, decoration storage, festive boxes, home organization, Christmas accessories, ornament organization, storage solutions, storage room boxes, decoration protection”,
“category_name”: “STORAGE”
}

Any insight or advice would be greatly appreciated. Thanks!
