The Index Audit page allows you to compare metrics from your current index with a previous version of the index. You can display only changed metrics, or all metrics in the audit. By default, the audit compares the current index to the previous index, and displays only the metrics that have changed.
You must have completed and deployed at least one index before you can use this tab, and two indexes before you can do a comparison.
To use Index Audit:
On the Projects tab, go to Projects > Your Project > Index Review.
Click the Index Audit tab.
Click the Select link to choose an index to compare to the current index. By default, the next most recent index is selected for comparison. If you only have one index, metrics for that index are displayed, but there is no comparison.
By default, only changed metrics are displayed. Click the All Elements button to show all metrics for both indexes, or click Changes Only to view only metrics that differ.
Note: The Topics loaded metric does not include default topics supplied in Search Administration, but only topics you explicitly add.
