I am getting 0 results for any ranges after 9/23/2015.
See last day of results here: https://api.fda.gov/food/enforcement.json?search=report_date:[20150923+TO+20160106]
No results from 9/24 on: https://api.fda.gov/food/enforcement.json?search=report_date:[20150924+TO+20160106]
Did the report_date property become deprecated? I am using report_date in my site's (https://defender.ionep.io) queries to get the previous 90 days -- reporting 0 results at the moment.
Also you can see in the example enforcements graph there are no results after 9/2015 https://open.fda.gov/food/enforcement/
