-|`time_in_nanos`	| The total elapsed time for this query, in nanoseconds. For concurrent segment search, `time_in_nanos` is the total amount of time across all slices (`max(slice_end_time) - min(slice_start_time)`).   |
+|`time_in_nanos`	| The total elapsed time for this query, in nanoseconds. For concurrent segment search, `time_in_nanos` is the total time spent across all the slices i.e. difference between end time of last completed slice execution and start time of first slice execution.   |

-|`breakdown.<method>`	| For concurrent segment search, this is the total elapsed time across all slices (`max(slice_end_time) - min(slice_start_time)`). For example, for the `build_scorer` method, it is the total time spent constructing the `Scorer` object across all slices. |
