simple 2i test that should print true 5 times in leveldb, but only 4 times with memory backend.

2i_key_test.rb

require 'riak'

c = Riak::Client.new(:nodes => [{:host => 'localhost', :http_port => 8091}]) 
b = c.bucket('foo')
ro1 = b.get_or_new('one')
ro1.raw_data = "Hello, world!"
ro1.content_type = "text/html"
ro1.indexes['date_bin'] << '2012-07-13'
ro1.store

ro2 = b.get_or_new('two')
ro2.raw_data = "Ola Mundo!"
ro2.content_type = "text/html"
ro2.indexes['date_bin'] << '2012-07-12'
ro2.store

ro3 = b.get_or_new('three')
ro3.raw_data = "Guten Tag!"
ro3.content_type = "text/html"
ro3.indexes['date_bin'] << '2012-07-11'
ro3.store

result = b.get_index('date_bin', '2012-07-11'..'2012-07-13')
puts 3 == result.length

result = b.get_index('date_bin', '2012-07-11'..'2012-07-12')
puts 2 == result.length

result = b.get_index('date_bin', '2012-07-11'..'2012-07-11')
puts 1 == result.length

result = b.get_index('date_bin', '2012-07-09'..'2012-07-10')
puts 0 == result.length

result = b.get_index("$key", 'two'..'two')
puts 1 == result.length

in riak 1.2rc1, toggle between {storage_backend, riak_kv_eleveldb_backend}, and {storage_backend, riak_kv_memory_backend}

We should add this to the riak_test for 2i. I'll look into that today, hopefully.
