Nginx rewrite for URI querystring value

Question

I changed my website platform and i am now getting hits from google pointing to the old location of tag searches on my site. Basically i need to point:

http://www.website.com/articles/Subject%3Alist=Music-Oldies&review_state=published

to:

http://www.website.com/tags/Music-Oldies

..in my Nginx website file. Only the tag 'Music-oldies' needs to be extracted. 'Subject%3Alist' is actually 'subject:list'.

EDIT: '....articles/subject%3Alist...' should have been '....'articles?subject%3Alist....'

Answer 1

You need a rewrite directive like this:

rewrite Subject:list=([^&]+) /tags/$1 permanent;
