Mitchoyoshitaka, first of all - thanks for YARP and for your work.
I have WordPress with russain language, YARP is working on my test setup, but wp_yarpp_keyword_cache contains no single russian(cyrilic) word! Only english(latin), sometimes containg on posts (like Mercedes, Star Wars etc).
Is this normal situation for YARP?
