RAG Learning

Learning Path

Level 1: Minimal RAG

Build working RAG with LangChain + Chroma in 30 minutes.

For step-by-step: See references/level1-minimal.md

Level 2: Core Components

Understand and experiment with each RAG component.

For details: See references/level2-components.md

Level 3: Real Documents

Handle PDF, web pages, tables. Build personal knowledge base.

For details: See references/level3-documents.md

Level 4: Optimization

Implement Hybrid Search, Reranking, better prompts.

For details: See references/level4-optimization.md

Level 5: Production

Compare frameworks, choose vector DB, add caching.

For details: See references/level5-production.md

Quick Reference

Frameworks by Use Case

Use Case	Framework	Why
Quick prototype	LangChain	Most examples, easy start
Data-heavy apps	LlamaIndex	Best data connectors
No prompting	DSPy	Programmatic LLM
Production RAG	RAGFlow	End-to-end solution

Common Issues

Problem	Solution
Chunk too large/small	Adjust chunk_size (500-1000 tokens)
Wrong embedding model	Try domain-specific model
Retrieved but wrong answer	Check prompt template
No results	Lower similarity threshold
Slow retrieval	Add caching, use hybrid search
