I have some bad news for you.

Kindle - not an ideal platform for dictionaries, alas. It demands that all of the forms of word to be defined in one dictionary entry. But there's no such dictionaries. E.g. ABBYY Lingvo (available for PC, iOS, Android; 20-languages version has Polish-Russian and Russian-Polish dictionaries, as I understood) dictionaries contain not the inflected forms, but some rules of words inflection and can search both "такой" and "такие". But the Kindle - cannot.
