Elasticsearch is very popular because it works well for generic searching and can be customized for lots of unique scenarios. There's competition on the infrastructure side using something other than Java/JVM though: For Rust, there's Toshi: https://github.com/toshi-search/Toshi https://github.com/toshi-search/Toshi which is built on top of Tantivy: https://github.com/tantivy-search/tantivy https://github.com/tantivy-search/tantivy For C++, there's Xapiland: https://github.com/Kronuz/Xapiand https://github.com/Kronuz/Xapiand For Go, there's Blast: https://github.com/mosuka/blast https://github.com/mosuka/blast built on Bleve: https://github.com/blevesearch/bleve https://github.com/blevesearch/bleve
