Theater search matches keywords (title, synopsis, creator) and structured filters written in plain words — "horror under 15 minutes", "PG drama", "documentary over an hour".
A title is returned only when it matches a keyword or a structured filter. Popularity and rating only order the matches; they never add unrelated titles. So a nonsense query returns nothing, not the whole catalogue.
When nothing matches, the page says so and shows "did you mean" chips — the nearest titles by spelling — so a one-letter typo still finds The Ashfall Signal.
Kids profiles search only the G and PG catalogue.
