The Previous Searches list displays a history of result sets numbered R1, R2, R3, etc. from most recent (R3) to oldest (R1). Result sets give a quick overview of the search expression, showing the type of search performed, your search terms and any search limiters, and the number of results (or "hits").
A Revise link is available for each result set. Click this link to return to the search input page used to create the search. Your search criteria will re-display, allowing you to make changes.
Result sets can be used when you build your own search expressions using CCL Advanced Search.
