 Description   

Under SERVER-2235, we added a new statistic called seeks for the IXSCAN query execution stage. This statistic is exposed via explain in "executionStats" and "allPlansExecution" modes. It reports the number of times that we had to seek the IndexCursor to a new position in order to complete the index scan.

We may want to extend our documentation of explain results to mention seeks:
