 With token-level vectors, models like ColBERT can match specific query tokens to the most relevant parts of a document, enabling high-accuracy retrieval through Late Interaction.
 
-In late interaction, each document is converted into multiple token-level vectors instead of a single vector. The query is also tokenized and embedded into various vectors. Then, the query and document vectors are matched using a different similarity function: MaxSim. 
+In late interaction, each document is converted into multiple token-level vectors instead of a single vector. The query is also tokenized and embedded into various vectors. Then, the query and document vectors are matched using a similarity function: MaxSim. You can see how it is calculated [here](https://qdrant.tech/documentation/concepts/vectors/#multivectors). 
 
 In traditional retrieval, the query and document are converted into single embeddings, after which similarity is computed. This is an early interaction because the information is compressed before retrieval.

 ## Conclusion
 Multivector search is one of the most powerful features of a vector database when used correctly. With this functionality in Qdrant, you can:
