Making RAG Accurate in Java
📰 Dev.to · Puneet Gupta
Improve RAG accuracy in Java using hybrid dense+BM25 search and evaluation metrics like recall@k and precision@k
Action Steps
- Implement hybrid dense+BM25 search using Java libraries like Apache Lucene or Elasticsearch
- Apply metadata filtering to narrow down search results
- Use chunking strategy to optimize search performance
- Measure recall@k, precision@k, MRR, and nDCG to evaluate RAG accuracy
- Configure Reciprocal Rank Fusion to combine multiple ranking models
