Filter in the same page?

Hi, I see here http://demo.designsandcode.com/sfpro-movie-reviews/search/

I can filter in the same page, but if I add filter in my site (homepage) results are open in a new page.

Example if I select tag “red” in filter results appear in http://mysite.com/tag/red/

Can I filter in the same page like first link?

Thanks
