From Search page, select a constraint with 1 result (applies also to any number of results smaller than the page size). Paging text says "1 - 20 of 1 results". When less than the page size, the "to" page should be the actual number of results, and the "results" ideally should be a singular "result" when there is just 1. E.g. "1 - 1 of 1 result."
