def kick
  Ultrasphinx::Search.new(to_hash).results
end

#page(number) ⇒ Object

Some magic to add pagination. This gets called if you were to do:

Meal.select {'bacon'}.page(5)

When page is invoked, it’s actually being invoked on Ambition::Context. It has method_missing? voodoo which will try to pass the method onto the Query. That’s this class.
