The proglem is that a search page url does not change when you do a search on yandex.com and advance to see more pages. It must be done somehow by javascript. Any ideas?

When you do a search page url actually changes. Though when you advance it doesn't.
That's done via AJAX.

Also, Yandex forbids parsing of their search results.

P.S. It's kinda strange that you asking it here. You better ask on some english-speaking forum.
