XERJ
An open-source AI data search and indexing tool written in Rust. Its core capability is autoindex automatic indexing, supporting the indexing and retrieval of code, documents, logs and PDFs. It is compatible with the Elasticsearch API and is used in scenarios such as RAG, security auditing and agent memory. Compared with grep, it can substantially reduce token consumption.
Timeline (last 90 days)
XERJ is an open-source project on GitHub positioned as a new way to search data for AI, with its core capability being autoindex (automatic indexing), which can index code, documents, logs and PDFs with a single command for use in scenarios such as search, RAG, security auditing and Agent memory.
XERJ claims it can save 40 times the Tokens compared with grep.
XERJ is written in the Rust language.
At the time of writing, XERJ had gained 4,751 stars and 295 forks on GitHub, with 725 new stars in a single day.
XERJ is compatible with Elasticsearch, and existing Elasticsearch clients can connect directly without modification.
Rust has advantages in memory safety and concurrency performance, but a higher contribution threshold may affect the accumulation of community contributors and the pace of feature iteration for early-stage open-source projects.
XERJ's autoindex leans more toward the structured/inverted index route rather than the vector retrieval route, and its value lies in using precise indexing to reduce irrelevant content entering the context.
For teams considering adopting XERJ, it is recommended to run benchmarks on their own real datasets before making a decision, because the 40-fold Token savings may differ significantly across different data scales and query patterns.
The data types XERJ supports include code indexing, documents and PDFs, log retrieval and Agent memory.
The project address is github.com/xerj-org/xerj.
