Elasticsearch

A new open-source project called XERJ has been released, positioning itself as a search tool built for AI agents. It indexes code, documents, logs and PDFs with a single command, and claims to use 40 times fewer tokens than grep while remaining compatible with Elasticsearch clients. It is written in Rust and aimed at RAG, security audits and agent memory use cases.

Michael Aleone, a career changer moving from highway construction into cybersecurity, is building a mini security operations center on Kubernetes in his home lab. He runs it as a fictional managed security provider defending an equally fictional manufacturing client, using tools like Elasticsearch to gain hands-on experience with enterprise IT and operational technology systems.
