I was wondering whether there's any correlation that find an expression in knowledge search results, between the '5 star' ranking of Salesforce knowledge article to the 'Yes/No' votes of customer on PKB articles. see explanation:

I see that it is possible to sort knowledge article search results by rating --> so wouldn't it make sense if the article rating will consider the customers votes (PKB) in addition to the '5 star' ranking?

Can you please shed light on this?
