Hi Roy,


In order to activate payloads during scoring, you need to do two separate things at the same
time:
* use a payload aware query type: org.apache.lucene.queries.payloads.*
* use payload aware similarity

Here is an old post that might inspire you :  https://lucidworks.com/2009/08/05/getting-started-with-payloads/

Thanks for your replies. But still, I am not sure about the way to do the
thing. Can you please provide me with an example code snippet or, link to
some page where I can find one?

Thanks..
