Catfish, searching files on Linux

I do not like the default search engine that has Ubuntu. He finds nothing, so it takes me less searching by hand to using a search engine. Sometimes Synapse use the search box that works pretty well, but still fails. That's why I liked this program that really meets the mission of finding files on Ubuntu, using different search engines.

To install on Ubuntu writes :

sudo apt-get install catfish

For Fedora writes :

yum install catfish

You can access it from Applications/Accessories/Catfish:

You can make a selective search folder and choose the file extension you wish to search. Also included in the search for hidden files. And most importantly: It works great!
