Need to reimplemented ukrainian build-in language analyzer as a custom analyzer (extend ukrainian analyzer with shingle filter).
In russian we have russian_stemmer that could be passed to custom analyzer.
In ukrainian_analyzer we don`t have access to ukrainian_stemmer.
Is it possible to reimplemented ukrainian build-in analyzer
and if not, maybe is possible to combine build-in analyzer with custom analyzer or extend with adittional token-fillters or access to ukrainian_stemmer of this analizer as a filter?
