Answer 1

From Arel documentation

The OR operator is not yet supported. It will work like this: users.where(users[:name].eq('bob').or(users[:age].lt(25)))

This RailsCast shows you how to use the .or operator. However, it works with Arel objects while you have instances of ActiveRecord::Relation. You can convert a relation to Arel using Product.name_a.arel, but now you have to figure out how to merge the conditions.
