sphinx находит не все и не ищет по части слова

подскажете, пожалуйста, вопрос по поиску в sphinx. По слову tiger находит - Bergepanzer Tiger I mit Borgward IV Ausf.A Heavy Demolition Charge Vehicle, а например - 2047 King Tiger Pz.Abt.505 Sd.Kfz.182 Henschel Turret не находи. И не на ходит по части слова, например - Немецкое самоходное противотанковое орудие Jagdtiger, в комплекте 2 фигуры Что поправить в файле конфигурации. Вот файл конфигурации
