Advanced RAG Techniques: Boosting Retrieval with Query Translation and Decomposition

The article examines how retrieval‑augmented generation suffers from poor query formulation and presents two advanced strategies—query translation, which generates multiple semantically similar variants, and query decomposition, which breaks complex questions into finer sub‑queries—detailing methods such as fan‑out retrieval, reciprocal rank fusion, HyDE, step‑back prompting, and chain‑of‑thought retrieval, and explains when to combine them.
