You can also add your own search phrase: just start typing your desired keyword and hit enter. This will append your custom keyword to the search string. When you're ready, click the red "Search" button to generate results.

You can also initiate a search by clicking on a specific filter, such as national lever of power, and select a subcategory, such as military. This will return results for publications that were coded as having information relevant to the military lever of power.
