Hi, may i know if there's any cross-encoder type reranking? Appreciate clarification on how we can perform reranking. Are the below steps correct?

use the retrieval Prompt.C encode
compare similarities and retrieve k number of relevant docs
Remove Prompt.C by setting 'prompt = None' and encode the k number of relevant docs found in step 2
rerank the k number of relevant docs based on embeddings from step 3

Hi, it doesn't support cross-encoder now.

The steps are correct. Prompts.C is applied for the query, not documents.

Thanks @SeanLee97 . May i confirm that these steps is also how the reranking benchmarks are achieved?
