Advanced Query Syntax missing in Windows File Explorer and Word 2013 File Search?

I recently installed some Windows updates and now Advance Query Syntax seems missing from the Search boxes in Windows File Explorer and the Word 2013 legacy Open dialog boxes, and I can no longer limit searches by date (create:, modified:, ect) or click and produce that little drop down calendar to use anymore. All the AQS search parameters that have colons at the end or their names don't work. Does anyone have any idea what those little clock icons mean and where they're from?
