Using My NCBI Filters
Click the steps to run the demonstration.
Click on a filter name to go to the citations for a particular filter.
Notice that when you choose to see the results for a filter, a plus sign appears to the right of the filter name.
Clicking on the plus sign adds that filter to the search query. Filters added this way will display in the query box with the [Filter] tag. If you want to save this search, click on the Create Alert link under the search box.
The video illustrates the directions that are on this page.
