Javascript-форум - помогите со js скриптом поиска по текстовой базе

у меня есть js скрипт он ищет по заданному ключевому слову похожее слово в текстовой базе и выдает страницу с найденным.Но,вот в чем проблема он ищет только по 50 словам,а мне нужно 2000 и более,подскажите в чем проблема.
Вот собственно скрипт:(он находится в самой базе daabase1.txt)
