This project, developed in rust, offers "retrieval-augmented generation" (RAG) capabilities for content gathered from the web.

Its core concept revolves around operating all essential components locally, thus avoiding reliance on external public APIs. This approach shares similarities with initiatives like privateGPT. The choice of rust as the programming language is primarily for educational exploration, rather than for performance optimization.

The project's name creatively merges "Rust" and "RAG," with a playful twist reminiscent of "ragamuffin," or even an allusion to "asparagus."

It comprises both a server and a client binary, with the flexibility to select either through the cargo --bin option.

There is a server and client binary. Use the cargo --bin to choose between.

Point it to upload some data like this:

# basic example
rust-a-rag-us upload --url https://docs.lagoon.sh/

# setting logger and using collections
RUST_LOG='info,rust_a_rag_us=debug' rust-a-rag-us --filter-collections="basic,summary" upload --url='https://docs.lagoon.sh/'

rust-a-rag-us drop

rust-a-rag-us query --query 'what lagoon service types can you in the docker compose yaml?'

# using cargo run
RUST_LOG=info cargo run --bin client -- --filter-collections="basic,summary" query --query 'what lagoon service types can you in the docker compose yaml?' --ollama_model openhermes2.5-mistral:7b-q6_K

You can also switch the model used by providing e.g. --ollama_model 'openhermes2.5-mistral:7b-q6_K'

• sitemap lookup does not recursively resolve sitemap pointing to another sitemap
• the ollama-rs streaming seems to be a bit brittle and fails with: Failed to deserialize response: EOF while parsing a list at line 1 column 8186
• make prompts configurable?
