Solr and Elasticsearch are the most popular search engines built on top of Apache Lucene. These are great tools, they do their job nicely. But the problem is they are written on Java that's why they usually consume a significant amount of server resources. Here are few resource-efficient alternatives written on Rust:

● Tantivy (★ 2,330) is a full-text search engine library inspired by Apache Lucene and written in Rust.
● Toshi (★ 2,056) is meant to be a full-text search engine similar to Elasticsearch. Toshi strives to be to Elasticsearch what Tantivy is to Lucene.
● Sonic (★ 6,118) 🦔 Fast, lightweight & schema-less search backend. An alternative to Elasticsearch that runs on a few MBs of RAM.
