Elastic Search No Server Available, List Index Out Of Range

I'm trying to get a simple example working with elastic search using pyes, but I'm having trouble getting the starting examples working. I'm following the documentation found here:

Solution 1:

This will work:

ES(server=[('http', 'localhost', 9200)])

Server is a list of tuples.

Documentation to this is here: http://pyes.readthedocs.org/en/latest/references/pyes.connection.html
