What are lnx and Weaviate?
lnx
lnx is an open-source search engine server built on top of the Tantivy library that exposes a simple REST API for indexing and querying documents. It aims to be a fast, easy-to-deploy alternative for full-text search.
- Built on Tantivy
- Simple REST API
- Fast full-text search
- Typo-tolerant queries
Weaviate
Weaviate is an open-source vector database that stores objects and their vector embeddings for semantic search. It enables AI-powered similarity search, retrieval-augmented generation and hybrid queries.
- Vector and hybrid search
- Built-in vectorization modules
- GraphQL and REST APIs
- Horizontal scaling
