Create a Query in Parse using Objective-C.

I'm having trouble programming a few small things in my iOS app. I need someone who is very familiar with Parse to write a PFQuery for me. This PFQuery will retrieve several arrays (around 10) stored in my Parse database for the current user, and then compare the data in those arrays with all the other users in the database for the same specific arrays. The users who have at least 1 intersect for any array will then be saved in an array and then displayed (In order from most intersections to least intersections). All of the above happens when the user does a search. They also have the ability to chose how many kilometres they want the user to be in (I already have a query for this), so if PFGeoPoint could be used with the first query, that would be great. I hope this makes sense. Please ask any questions if you have any. Cheers.
