Filter Information

Filters allow you to refine your search results by specifying additional criteria. Filter options appear to the left of your results. To apply filters: 

  • Click on a filter to apply it to your search. Active filters appear above your search results.
    • Filters "stick" and are applied to future searches until you turn them off.
  • You may be able to  select multiple filters within a single category.
    • For example by selecting Clinical Trial and Review under the Article Type category, you are limiting results to either Clinical Trial or Review articles.

To view a detailed graph of publication dates, click the expand icon to display an expanded view from which you can set the publication date filter. 

Only the most popular filters are displayed by default.
