Alvar

Alvar (formerly known as Sajari) represents the 2026 benchmark for intelligent site search, utilizing a hybrid architecture that blends traditional keyword matching with sophisticated neural vector search. Its core technical differentiator is its built-in Reinforcement Learning (RL) layer, which autonomously optimizes search rankings based on real-time user interaction data such as click-through rates and conversion events. The platform is designed for high-scale e-commerce and content-heavy enterprises that require sub-100ms latency across global indices. Alvar's 'Pipelines' feature allows developers to programmatically control the search experience using a visual or code-based logic editor, enabling complex custom ranking factors, synonym handling, and dynamic faceting. As of 2026, Alvar has positioned itself as a primary competitor to Algolia and Elastic, specifically targeting organizations that want the power of vector search without the overhead of managing specialized infrastructure. It integrates deep telemetry to provide actionable insights into 'no-result' queries and trend forecasting, making it a critical component of the modern headless commerce stack.
