restful url settlement search

i'm looking reasonable proceed paint searches calm urls.

the setup: i have twin models, cars garages, where cars garages. urls feeling like:

/car/xxxx
  xxx == car id
  advantage car given id

/garage/yyy
  yyy = garage id
  advantage garage given id

a car exist the possess (hence /car), exist garage. what's right proceed represent, say, cars given garage? something like:

/garage/yyy/cars     ?

how kinship cars garage yyy zzz?

what's right proceed paint hunt cars certain attributes? say: arrangement me blue sedans 4 doors :

/car/search?color=blue&type=sedan&doors=4

or should /cars instead?

the "search" seems unapt there - what's improved proceed / term? should only be:

/cars/?color=blue&type=sedan&doors=4

should hunt parameters biased pathinfo querystring?

in short, i'm looking superintendence cross-model rest url design, search.

[update] i justin's answer, nonetheless doesn't cover multi-field hunt case:

/cars/color:blue/type:sedan/doors:4

or something that. from

/cars/color/blue

to churned domain case?
