Show HN: Gemma 4 based local RAG on 25 Years of news articles

https://github.com/r-follador/TeletextSignals/

A fully local Retrieval-Augmented Generation (RAG) implementation for querying 25 years of Swiss Teletext news (~500k articles in German language) - based on Deepmind's most recent Gemma model.

Why? I thought it's a cool type of dataset (short/high density news summaries) to test some local RAG approaches. Gemma 4 gives some impressive results, but could probably use some more tweaking on the system prompt.
