It is the second form on the page because the PowerCMS Search box is the first form on the page.
But, while I understand that I could easily just change the form array from forms to forms, it still doesn't identify the correct inputs. For example, if I had fields such as blogdate and blogtitle - instead of identifying them as forms.blogdate, etc.; it instead makes everything I want to validate say forms.S_keyword referring back to the only field in the search form, even though I have specifically selected the input in the second form.
The only way to correct it, while inconvenient, has been to go into the "tag" behaviors and adjust them individually. Is this the only way to do this, or is that just a nuance of client validation? I would also be ok with using server validation if there was a way to create the automatic date reformatting such as the way you can do that in client validation.
