To display a list of pages, we built up a query and following is a part of it. 

blogsQuery = blogsQuery.OrderByDescending(x => x.LikeCount);  

Strangely, it does not sort the results in descending order of the likecount. 

However, for another filteration, it does work. The difference here is LikeCount probably returns values on the fly. Meaning it's defined as follows in the blog page. 

public virtual int LikeCount
{
    get
    {
        return LikedUsers?.Count ?? 0;
    }
}

and finally the result retrieved

 var result = blogsQuery.Take(MaximumResultsPerRequest).Skip((pageNum - 1) * MaximumResultsPerRequest).GetContentResult();

Is this a limitation of Search and Navigation ? Is there a workaround ?
