Get Modified documents in a date range smaller than a day.

Hi, I am currently trying to use the XML Search API (or REST API) to retrieve modified documents in let's say the last 15 minutes. I know that with this request : http://hostname/OTCS/cs.exe?func=search&outputformat=xml&lookFor1=otstarts&where1="" range "20180319~20180320"&startAt=1&goFor=50 , I can retrieve the modified documents in the last day. However, it seems impossible to retrieve documents in a range of hours or minutes. Is there any hidden endpoint or documentation allowing this? Any idea how I can accomplish this in Content Server?
