Django: Search URL for keyword RegExp
Part after the ? not used in the url dispatching process because it contains GET parameters. Otherwise you will not be able to use a GET request with parameters on patterns like r'^foo/&' (ampersand at the end means the end of the string, and without it it would be harder to use patterns like r'^foo/' and r'^foo/bar/' at the same time). 
So for your url the pattern should look like r'^databaseadd/q=DQ-TDOXRTA&' and then in add_recipe view you need to check for the recipe GET parameter.
I have the following URL:
http://127.0.0.1:8000/databaseadd/q=DQ-TDOXRTA?recipe=&recipe=&recipe=&recipe=&recipe=
I'd like to match if the keyword "recipe=" is found in the url. 
I have the following line in django url.py but it's not working:
url(r'recipe=', 'plots.views.add_recipe'),
Are the  "&" and the "?" throwing it off?
Thanks!
