This post is very helpful found at http://appengine-cookbook.appspot.com/recipe/how-to-query-by-date-range
Often, you need to store, and retrieve, data that needs to match an "effective date period", containing a "start date" and "end date". ... You can handle your query if you add another field in your Kind, a ListProperty containing both the start date and end date. For example, add a ListProperty named "date_list", and populate it like this: date_list = [start_date, end_date]. My Question. In Java, what constitutes a ListProperty. I assume ArrayList. I am hoping that an int[] also counts because this has much less overhead to store. Does anybody know or know where the rules for ListProperty might be found.
