Talks
Building Delivery Hero’s Product Semantic Similarity Using Atlas Vector Search
John Underwood (MongoDB) & Fahad Yousaf (Delivery Hero)
Delivery Hero’s Quick Commerce service provides customers with an easy and efficient way to order grocery items for delivery. However, with thousands of stores and millions of products available on the marketplace, the company faces the risk of revenue loss and customer churn if users struggle to find products that meet their needs and preferences. This talk will explore how Delivery Hero developed a product semantic similarity recommender using transformer-based product embeddings and vector search to identify similar products across various points in the customer’s purchasing journey. We will also discuss the challenges encountered, the solutions implemented, and the next steps for this initiative.

From Zero Results to Vector Search: Insights from Nine Key Experiments
Abel Camamacho Guardian & Joel Widmer (Digitec Galaxus)
This session will explore the structured approach we used for experimentation to enhance the user search experience at Digital Galaxus.
We conducted nine key experiments, including four focused on improving the embedding model; one incorporated new signals such as product availability to increase add-to-cart rates, and another optimized latency through vector quantization and the transition from brute-force search to HSNW. Additionally, we examined cases where displaying a zero-results page was more effective than showing vector search results.
About the speakers
