LanceDB WikiSearch: Native Full-Text Search on 41M Wikipedia Docs

WikiSearch is a demonstration search engine that efficiently combines Full-Text Search (FTS) and vector search to provide a hybrid search solution for applications requiring precision, scale, and simplicity. Utilizing LanceDB Cloud, it processes and indexes 41 million Wikipedia entries, achieving impressive performance benchmarks, such as processing over 60,000 documents per second and building vector indexes in 30 minutes. The system leverages FTS for keyword precision and vector search for semantic relevance, merging both approaches to deliver precise and contextually relevant results. By offering a native FTS solution within LanceDB, it eliminates external dependencies and enhances performance. The platform supports various configurations, including tokenization and multilingual handling, allowing users to fine-tune search parameters. LanceDB's scalable design ensures efficient data ingestion and real-time application support, providing a robust framework for developing RAG applications and semantic search engines.
