+## Colbert Reranker
+
+Uses Colbert V2 model as a reranker to rerank documents according to the fine-grained similarity between query tokens and passage tokens. Returns the top N ranked nodes.
+
+```python
+from llama_index.postprocessor.colbert_rerank import ColbertRerank
+
+colbert_reranker = ColbertRerank(
+    top_n=5,
+    model="colbert-ir/colbertv2.0",

+    keep_retrieval_score=True,
+)
+
+query_engine = index.as_query_engine(
+    similarity_top_k=10,
+    node_postprocessors=[colbert_reranker],
+)
+response = query_engine.query(
+    query_str,

+## Jina Reranker
+
+Uses models from [jina](https://jina.ai/) to rerank documents. Returns the top N ranked nodes.
+
+```python
+from llama_index.postprocessor.jinaai_rerank import JinaRerank
+
+jina_rerank = JinaRerank(api_key=api_key, top_n=2)
