Ohm, find all records from array of ids

I am looking for a way to find all Ohm affiliated objects with one query, by feeding it an array of attributes that are indexed. In Mongoid, this is done with something like:

Foo.any_in(:some_id => [list_of_ids])
 

ActiveRecord has the find_all family of methods.

I essentially want to be able to pull N records from the data store without calling find() 30 times individually.
