I want to write a request on the search result request webpart. My request should enables me to retrieve all documents that have the biggest number of likes. There is no variable for the number of likes proposed on the drop list while writing a request , that why I decided to set a refinableInt00 variable and give it the value : LikesCount but it doesn't work? it means that LikesCount doesn't exist as a variable on sharepoint so what is the variable on sharepoint that would enable me to have the number of likes?
