=head1 NAME

Data::ObjectDriver::Driver::MultiPartition - Search thru partitioned objects without
the partition_key

=head1 DESCRIPTION

I<Data::ObjectDriver::Driver::MultiPartition> is used internally by 
I<Data::ObjectDriver::Driver::SimplePartition> to do very simple
search accross partition, if the terms of the query cannot be used to
determine the partition.

It's just a basic support. For instance 'limit' arg isn't supported
except if its value is 1.
