A Conversation with Paul Masurel, Creator of Tantivy

Paul Masurel, creator of the Rust search library Tantivy and co-founder of Quickwit, which Datadog acquired in 2024, is the subject of an interview published April 2, 2026, tracing the engine's rise as a challenger to Apache Lucene, the Java library that has dominated full-text search for two decades. Masurel began Tantivy in 2017 as a spare-time project to test his understanding of search engines and learn Rust, after reading the Rust book on a 2016 Tokyo-to-Paris flight while working in Indeed's search quality team on a Lucene 2.4-based engine; his earlier search experience included a front-end role at French enterprise search firm Exalead. Tantivy has since become the engine behind Quickwit, ParadeDB, and LNX, and has prompted a performance collaboration with the Lucene team itself. The interview matters because it signals growing momentum for Rust-based search infrastructure at a time when Lucene underpins Elasticsearch, Solr, and much of the industry's search stack. Watch for further adoption of Tantivy-based products and continued cross-engine collaboration between the Rust and Lucene communities.
