From looking at postings so far, my guess is it's not natural for the submitters to remember or accurately list the job params as you've laid out.

My suggestion would be, if you're not already doing/working on it, to start doing some basic NLP around the specific verbiage used for each param, and then you can organize by match instead of by position in the list. I'm betting you'll see some nice results without much optimization even since each expected param argument is pretty different from one another.

Just an idea, best of luck!
