Can visitors search the articles on my News page?

Yes, and it is already on. Every News page shows a search box above the article grid: visitors type a word and the grid narrows to the articles whose title or summary match, including an article currently featured at the top. Clearing the box brings the full list back.

Next to it are Categories and Subjects. Each is a heading that opens to a list with the number of articles beside every name, so a visitor can narrow to one, and a long list has its own search box. When your news carries stories from two or more outside publications, a Sources heading lists them the same way, so a visitor can see one outlet's stories. A Sort dropdown switches between newest first and oldest first. Load More reveals the next batch. How many articles show before that first press is the News Index block's How Many In The Grid setting, in the page editor. Articles Across, on the same block, sets the most cards in a row (3, 4 or 5) when the Layout is Cards; Automatic sizes the cards to the page.

This searches news articles only. The episode search on your Episodes page is separate.
