Tổng quan
XERJ provides an autoindex capability that allows AI agents to efficiently search and retrieve information from local datasets without the token waste associated with tools like grep or sed. By pointing XERJ at a directory, it automatically infers datasets, parses files using tree-sitter for AST-aware code indexing, and makes the data queryable. It implements the Elasticsearch REST API, achieving high conformance (1360/1363 cases), meaning existing Elasticsearch clients, dashboards, and libraries can connect to it directly. It is written in Rust and distributed as a single static binary with no JVM or external dependencies.
