RAG Pipeline Blues
[Intro] (slide guitar, slow stomp) Ingest it. Chunk it. Embed it right. Index it. Retrieve it. Rerank it tight. [Verse 1] The answer came smooth, but the source was wrong, and the team kept polishing the final song. They tuned the prompt till the dawn turned blue, but the right little clause never made it through. [Pre-Chorus] (call and response) Where did it vanish? (In the pipe.) Where do you fix it? (At the site.) [Chorus] I got the RAG pipeline blues, if it did not retrieve, it cannot believe. Chunk by the shape, index by the use, rerank before you let it leave. Ground it in sources, cite what it drew, or the answer will sing what it never knew. I got the RAG pipeline blues. [Verse 2] Legal clauses need their borders kept, code needs paths where the symbols slept. Product IDs need exact-match fire, policy prose needs semantic wire. Small stable corpus? Maybe load it whole. Giant living knowledge base? Search is the soul. [Verse - Rap] (gritty spoken rhythm) Ingest for freshness, permissions in line, chunk by section, not a random sign. Embed the query like a query, document like docs, filter by tenant before the context unlocks. Dense for meaning, sparse for the phrase, hybrid when the real world mixes both ways. Rerank for precision, inject with a label, then test if the answer is source-grounded and stable. [Chorus] I got the RAG pipeline blues, if it did not retrieve, it cannot believe. Chunk by the shape, index by the use, rerank before you let it leave. Ground it in sources, cite what it drew, or the answer will sing what it never knew. I got the RAG pipeline blues. [Bridge] (harmonica break) Stale corpus? Refresh the store. Wrong tenant? Lock the door. Too few chunks? Recall is thin. Too many chunks? Noise comes in. [Final Chorus] (full band, call and response) I got the RAG pipeline blues, trace every stage till the evidence breathes. Ingest, chunk, embed, index, retrieve, rerank, inject what it needs. Ground it in sources, test what is true, or the answer will sing what it never knew. I got the RAG pipeline blues. [Outro] (slide fades) Do not tune the ending if the evidence never arrived.
