Your users search for “comfortable shoes for standing all day” and get shoe polish. 30% of searches return zero results even when products exist. This is keyword hell, costing you customers daily.

This session reveals how we transformed Adobe Commerce search using OpenSearch’s vector search capabilities. Learn the complete technical journey, including text embeddings, k-NN similarity, and hybrid search that combines keyword precision with semantic understanding.

We’ll cover the architecture, including vector indexing with FAISS and Lucene, ingest pipelines for automatic embedding generation, and query-time optimization.

Honest challenges included computational costs, embedding model selection through sentence-transformers comparisons, dimension tradeoffs between 384 and 768, cold start problems, and explainability to stakeholders.

You’ll get actionable knowledge such as exact OpenSearch configurations, PPL queries for semantic search, hybrid scoring strategies, open-source model recommendations, and cost optimization for Indian startups, with $30 per month infrastructure compared to $200 or more for managed vector databases.
