Let's clean up the Ruby example a bit, shall we?

  collection = Braintree::Transaction.search do
    order_id.begins_with?       "a2d"
    customer_website.ends_with? ".com"
    billing_first_name ==       "John"
    status.in?                  Status::Authorized, Status::Settled
    amount.between?             "10.00", "20.00"
  end

  collection.each do |transaction|
    puts transaction.id
  end
