Search items that are unused (eg, disapproval:none and order:custom) should be removed from the auto-completion list. Some items (such as disapproval) would be nice to have implemented in the future, but if it is non-functional, it should not be listed as an option.

You don't learn ruby, you stumble through it until it works
