In the [search input](https://github.com/observablehq/inputs/blob/main/src/search.js): `[^\\p{L}-]` appears to translate to: “the character before the term must not be a letter or a hyphen.” Consequently, if I am looking searching for 'round' and expecting 'merry-go-round' I do not find it. Is this intentional?
