The architecture backbone of modern AI search engines, RAG pipelines, and recommendation systems
Better embeddings. Better chunking. Better reranker. Almost nobody optimizes for the fact that "top 5 most similar" can mean "the same sentence, five times."
It's not a RAG problem. It's a "does your system know what 'it' means" problem - and it shows up everywhere language meets action.
Most of the tutorials stop at the “embed the query, use cosine similarity” but the magic of RAG is in something else…
Let us be honest. Right now, the sheer number of options surrounding us as developers is overwhelming. Every single day, a new architecture, a new buzzword, or a new framework drops — and we are left staring at our screens wondering which strategy to opt for.
