Advanced search assists you in building complex searches more easily than the standard methods. Any or all input boxes and filters may be used. If you click 'Go' without providing any terms or filters, then all datasets will be returned in the results list.
Enter all terms which must appear in your results in the "all of these words" box. If you wish to search on a specific phrase then enter the phrase in the "this exact wording or phrase" box. Enter any terms that may appear in the results but are not required to appear. Last, enter any terms that must not appear in your results list in the "none of these words" box.
Filters for location, date, or data type may be added to your search results by selecting from the drop down lists for each.
