Lucidworks Fusion is an enterprise search and discovery platform based on Apache Solr and Apache Spark. The platform supports cloud, hybrid, and on-premises deployments and can be operated in a cloud-native manner via Kubernetes. It is designed for companies with complex data landscapes and is suitable for both enterprise search and product search in e-commerce.

Through the Signals Beacon, Fusion captures user signals such as clicks, search queries, and navigation paths to continuously optimize the relevance of search results using machine learning. This is complemented by Neural Hybrid Search, which combines traditional keyword search with semantic vector search to deliver search results that are both precise and context-aware.
