Indexing virtual attributes breaks fuzzy update

[airblade]

The README says:

your searchable fields do not have to be stored, they can be dynamic methods too

I have a class like this:

class Employee < ActiveRecord::Base
  fuzzily_searchable :name
  def name
    "#{first_name} #{last_name}"
  end
end

– where :first_name and :last_name are columns in my employees table.

Fuzzily happily indexes the names and searches them. However any update to a record throws an error because fuzzily's after_save callback executes:

record.send("#{field}_changed?".to_sym)

– and the name_changed? method doesn't exist (and isn't created by active record).

[airblade]

A workaround is to define that method explicitly:

class Employee < ActiveRecord::Base
  # ...as above...
  def name_changed?
    first_name_changed? || last_name_changed?
  end
end

I can't see an obvious way to work around this, so I'll mention it in the README (unless you have suggestions). Thanks!
