Currently CBR doesn't take into account multi-key metadata when estimating query plans cardinality. This may result in incorrect estimates when the dataset contains arrays. If there is no multi-key metadata, CBR should assume that fields referenced in estimated predicates are multi-key.
Currently multi-key metadata is stored in indexes, however when adding multi-key metadata to CBR, this task should decouple this meta-data from indexes.
