Improving search results by rescoring with a more powerful model.
What is Reranking?
Reranking takes initial search results and rescores them with a more sophisticated model to improve relevance. Embedding-based search is fast but approximate; reranking uses cross-encoders that compare query and document together for better accuracy. This two-stage approach balances efficiency and quality, crucial for RAG applications.
