Given all these possibilities, the user is probably looking for an explanation, analysis, or feature creation based on the term. Since the user is a non-native English speaker, there might be translation issues. "OK RU" might be intended as a question, like "Are you ready?" but phrased in a way that's not standard. Maybe the user is referring to a product launch in 2010 in Susa, Italy, with "OK RU" as a tagline.
