Agentic, generative, and classic search in one retrieval platform
Deliver AI-driven keyword and neural results so users find what they are looking for quickly.
Generate suggestions from behavioral cues and personalize results for each user across their journey.
Let shoppers ask questions in natural language and receive grounded answers via retrieval-augmented generation.
Pin products, promote campaigns, and adapt ranking strategies on category and collection pages without engineering support.
Open-source, high-performance vector search at any scale
Built entirely in Rust with SIMD and a custom Gridstore storage engine for fast, scalable vector search.
Combine dense and sparse vectors in one query, supporting BM25, SPLADE++ and miniCOIL for keyword-plus-vector retrieval.
Store metadata as JSON and apply advanced filters such as nested, text, geo and has_vector, with filters applied during HNSW traversal.
Asymmetric, scalar and binary quantization reduce memory usage by up to 64x while preserving search quality.
