      This test case fails when the outer collection is sharded but the inner collection is unsharded (in this situation the pipeline is split and it requires a merging shard). The aggregation is failing to detect the dependency on the $text score metadata and executes it without error, when an error was expected. The result is then missing the 'score' field.
