To query the Github API with 'rest_client' I do the following, if I want to search for users in London:
require 'rest_client'
response = RestClient.get 'https://api.github.com/search/users', {:params => {:q => 'location:london'}}
Direct browser query:
How would I construct the query if for example, I wanted to match users that joined at or after May 11th, 2013?
Reference: https://help.github.com/articles/searching-users#created
If I were to directly input this query using a browser I would do
https://api.github.com/search/users?q=location:london%20created:2013-03-06
