Nixiesearch

Nixiesearch is a cloud-native, open-source search engine: it runs Apache Lucene over S3-compatible storage, delivering stateless operations and integrated AI features (RAG, vector search).

This is a modern, 'batteries included' search engine built on battle-tested Apache Lucene, supporting 39 languages, facets, and advanced filters. Its core strength is operational simplicity: it decouples compute and storage, running stateless search nodes against immutable indexes on S3-compatible storage. This design eliminates cluster state headaches, enabling zero-downtime blue-green deployments and risk-free schema changes. Nixiesearch integrates AI out of the box, offering fully local embedding and LLM inference, plus first-class RAG API support, all within a single container.
