Такі форми видають аналогічні помилки

[myroslavve]

У всіх випадках помилка стається тому, що datamuse не рахує пробіли як букви. Наприклад для паттерну: "????vu" (6 букв) datamuse поверне "deja vu", що є 7 символів, але 6 букв. Тому вирішення цієї проблеми залежить від #156

[danmysak]

У такому випадку я б додатково пропонував здійснювати внутрішню перевірку на відповідність поверненого результату заданому патерну: хто знає, які ще несподіванки у матчингу підготував нам Datamuse.
