SearchBetter: query rewriting for search engines on small corpuses (Harvard research project)

[VLSP 2025] ViDRILL is a Vietnamese document retrieval system for VLSP 2025. It combines dense and sparse retrieval, reranking, and optional LLM-based query rewriting and reasoning to support high-accuracy information retrieval and future LLM-enhanced pipelines.

Implementation query expansion in semantic meta-search engine. The resulting expansion system is called Wiki-MetaSemantik.

Advanced RAG pipeline optimization framework using DSPy. Implements modular RAG pipelines with Query-Rewriting, Sub-Query Decomposition, and Hybrid Search via Weaviate. Automates prompt tuning and few-shot selection using GEPA, SIMBA, MIPRO, COPRO, and BootstrapFewShot optimizers on datasets like FreshQA, HotpotQA, TriviaQA, Wikipedia and PubMedQA.

It shows an advanced RAG with Reflection where LangGraph is used for workflow management.

🚤 User and policy management component for KorAP, capable of rewriting queries for policy based document restrictions.
