I have an exposed filter on a date value that has it's granularity set to month, so it shows possible year and month values in the form. If I select just a year, no results are returned, even though I know there are posts that should be retrieved based on the year. If I then specify a month, all posts from that month and year are returned.
I need to be able to return results from the entire year when just year is selected. I'm thinking there might be a way to alter the granularity somehow during the request based on whether or not the month was specified? Any thoughts?
