Looking for theme that has inbuilt support for search and filter post by taxonom

I am looking for a wordpress theme that has internal support for search and filter post by taxonomy. Something like what has been implemented in this theme but this theme has been specifically designed for real estate. My website is not of such commercial nature but more of a knowledge portal and such a filter feature is needed for easy dissemination of information. Can anyone suggest any theme having such feature and of more general nature.
