By "queries", do you mean an NSFetchRequest? If so, here is a simple example:

Say you have an entity named Car, and it has a license plate number named "licenceNumber" of NSString type.

NSFetchRequest *request = [[NSFetchRequest alloc] init];
[request setEntity:[NSEntityDescription entityForName:@"Car" inManagedObjectContext:yourObjectContext]];
[request setPredicate:[NSPredicate predicateWithFormat:@"licenceNumber==%@", theLicensePlateNumberYouWant]];

Saying that, you may want to spend some time reading Apple's documentation first.
