What should I do if there are links from www in Yandex when the site has moved to without?

Question

Search Engine Optimization

About two months ago the site was on www.
Then he moved, strangling them in the search engine, setting up a redirect to without www.
When I drive in the query "host:www.sitename.ru" into Yandex, about 40 pages are displayed, when "host:www.sitename.ru" is only three.
1) Is this factor important?
2) If yes, how to fix the situation?
Thanks, colleagues.

Answer 1

Yandex webmaster has an option to move to another domain
