Rails - Apr 2007 - finds on child models

i''ve looking for the sql to do a comparison of objects in a
model''s
has_many objects. specifically it''s  a simple model:

class Person
   has_many :things
end

class Things
   belongs_to: person
end

i can save the person and their 3 (or however many) things.  now i
just need a way to search their 3 things against all other people''s 3
things to see if they''re the same.  for instance.

@person.thing 1 = ''baseball''
@person.thing 2 = ''tire''
@person.thing 3 = ''shovel''

what''s the sql (and it it possible with #find to return a collection
of people with the same things that the person searching using 3 text
fields has?
