Best way to find records where date != today

In a method, I want to find records where the stored date is not today.

I’ve done this

controller.find()
process_date_time = '!#' + utils.dateFormat(application.getTimeStamp(), 'dd-MM-yyyy') + '|dd-MM-yyyy';
controller.search()

Is there a better way than this? It seems wordy for a simple request.

Nope, this is how you do it.
There are other ways but those even take more code.
