Records with the highest relevance rank will be displayed at the top of the results list. By contrast, a rank by year will display the most recently published records at the top of the results list.

To organize your results list by rank, choose a rank option from the drop-down list. The default option is no ranking. Only the 1000 most highly-ranked records will be displayed.
