I'm building a math bot that, before anwering, verifies that the answer aligns with my countries formulas and explanation as each country has its small differences. So essentially I have a collection of structured md files full of formulas exactly as they are teached in our country with explanation. The platform would run on Gemini's API, but I want to have the extrenal knowledge base it should align with. The context is only about 10 pages, but chunked into 84 md files How to build this RAG systen most effectively, or are there simpler options other than RAG?
