Document Ingestion: The 15 Hidden Steps Before RAG Embeddings
A developer tutorial reveals that building a reliable RAG system requires 15 steps before embeddings, including file hashing, PDF parsing, text cleaning, chunking, and deduplication. Skipping these steps leads to silent failures and wrong answers. The guide emphasizes content-based hashing over filename hashing to detect changes and prevent duplicate processing.
