Piwik - Keyword not defined. How to determine?

Question

Analytics

Hello!
I decided to test Piwik, because 14 days of Yandex.metrics are not enough. While installed. I'm studying.
But I ran into such a problem - all transitions from Yandex are written - the keyword is not defined, although the metric shows the keyword.
Can I somehow make Piwik show the keyword from Yandex? I know that Google does not show, but Yandex gives in the metric.
Thanks for the help.
