 The above code sample shows an example of neural sparse search. Although there is no overlap token in original query and document, but this model performs a good match. 
 
 ## Performance
-This model is trained on MS MARCO dataset. The search relevance score of it can be found here (Neural sparse search bi-encoder) https://opensearch.org/blog/improving-document-retrieval-with-sparse-semantic-encoders/.
