In comment by within date

[Anand]

Hi Experts, 

Please can you help me where I am making a mistake 

I tried the following none seem to work and looks like I am not interpreting the help right. 

• assignee = abc AND issueFunction in commented("by abc before Date '-7d' ")
• assignee = abc AND issueFunction in commented("by abc before Date '2022/02/14' after Date '2022/02/07' ")
• assignee = abc AND issueFunction in commented("by abc before Date 2022/02/14 ")

Help is Appreciated 

Regards

[Anand]

Just wondering, if I have posted in the wrong space ?
