Since the default 'pip search' inst working anymore and returns an error, I've made a simple python script called "pypi-search" that I use instead. It gets search results from pypi website and prints them to the terminal.
Sourcing the bashfunction in my .bashrc allows me to keep using the command 'pip search module', because bash then calls my pypi-search script instead of pip(1), while it uses the original pip for anything other than a search.
