Tantivy - Full-text search engine library inspired by Lucene and written in Rust

Tantivy is a full text search engine library written in rust. It is closer to Lucene than to Elastic Search and Solr in the sense it is not an off-the-shelf search engine server, but rather a crate that can be used to build such a search engine.

Its features include:

• Full-text search
• Configurable tokenizer (stemming available for 17 Latin languages with third party support for Chinese (tantivy-jieba and cang-jie), Japanese (lindera and tantivy-tokenizer-tiny-segmenter) and Korean (lindera + lindera-ko-dic-builder)
• Fast (check out the 🐎 ✨ benchmark ✨ 🐎)
• Tiny startup time (<10ms), perfect for command line tools
• BM25 scoring (the same as Lucene)
• Natural query language (e.g. (michael AND jackson) OR "king of pop")
• Phrase queries search (e.g. "michael jackson")
• Incremental indexing
• Multithreaded indexing (indexing English Wikipedia takes < 3 minutes on my desktop)
• Mmap directory
• SIMD integer compression when the platform/CPU includes the SSE2 instruction set
• Single valued and multivalued u64, i64, and f64 fast fields (equivalent of doc values in Lucene)
• &[u8] fast fields
• Text, i64, u64, f64, dates, and hierarchical facet fields
• LZ4 compressed document store
• Range queries
• Faceted search
• Configurable indexing (optional term frequency and position indexing)
