Range Finding

If you have a range index, Dynamoid provides a number of additional other convenience methods to make your life a little easier:

User.where('created_at.gt': DateTime.now - 1.day).all
User.where('created_at.lt': DateTime.now - 1.day).all

It also supports gte and lte. Turning those into symbols and allowing a Rails SQL-style string syntax is in the works. You can only have one range argument per query, because of DynamoDB inherent limitations, so use it sensibly!
