from the api docs:
search_each(query, options = {}) {|doc, score| ...}
you see that ferret hands you two arguments into the block.
Now if you only accept one parameter, Ruby guesses that you want
all parameters as an array. This should yield a warning like
'multiple values for a block parameter (2 for 1)'
somewhere in your logs.
So just use |id, score| and everything should be fine :-)
cheers,
Jens
