How do I find a lost fanfiction on the internet?

I'm looking for a fanfiction.net story about rory and jess from gilmore girls. it starts out with them running away together and along the road he gets stabbed they get kidnapped. its a really angsty story i read a few years ago and i really wanted to re-read and can not find any where on the site. it was a VERY long fanfiction. does anybody know for me how to find it?
