Hi Johan, thanks for the reply
I would agree that it's ok, if I am searching for common term, like 'venue', 'club' or 'bar', but when it comes to User names, it make sense to score the position in the field too, because when you search in field user.name, and type 'Jo' you would expect first to see users with first name Joe, Johan, John, rather than having users with Jo in the family. And especially when you search for user name field you don't expect to have more occurrence of the name in that field.
