E-Commerce Semantic Product Search

A product search engine that understands what shoppers mean, built and measured on a laptop CPU. Keyword search (BM25) and semantic search with BGE embeddings are combined into a hybrid search, and a cross-encoder reranks the best candidates. Everything is evaluated on 1,000 real Amazon shopping queries with graded relevance labels (ESCI) and also runs inside OpenSearch.
