Media monitoring: the “Required” checkbox

All filters in the topic definition also have a "Required" checkbox. This allows users to specify that articles and events must meet at least one of the conditions defined in a specific group (interests, categories, event locations, etc.). In the case of the selected conditions demonstrated in the picture below, only the news articles and events that mention at least one of the specified concepts – “Tropical cyclone”, “Drought” or “Flood” would appear in the feed.

If the "Required" checkbox is unchecked, the articles and events will appear in the results even if they only match other required conditions.
