How is colbert v2 implemented in

Do you mean for reranking? https://docs.llamaindex.ai/en/stable/examples/node_postprocessor/ColbertRerank/

https://github.com/run-llama/llama_index/blob/main/llama-index-integrations/postprocessor/llama-index-postprocessor-colbert-rerank/llama_index/postprocessor/colbert_rerank/base.py

Or the index?:
https://docs.llamaindex.ai/en/stable/examples/managed/manage_retrieval_benchmark/?h=colbert#colbert-v2-managed-index-and-retrieval

https://docs.llamaindex.ai/en/stable/api_reference/indices/colbert/?h=colbert

https://github.com/run-llama/llama_index/blob/main/llama-index-integrations/indices/llama-index-indices-managed-colbert/llama_index/indices/managed/colbert/base.py

Thankyou, for both the resources. I actually wanted both re-ranking and PLAID based indexing
