You can as well try with timestamp in the unix timestamp.
Example: (( last_mod_by ='ServiceDesk' AND ) && ( last_mod_dt > 1722537000 ))
Note: 1722537000 is 1st August 2024.

Hi Katherine,
Try the query as:
last_mod_by ='ServiceDesk' AND last_mod_dt > StartAtTime ( 'TODAY' )
last_mod_by ='ServiceDesk' AND last_mod_dt > StartAtTime ( 'LAST_MONTH' ) --> change the username as per your requirement.
Below is the sample screeenshot with result.

Thanks & Regards,
Hema.

Subject: Find Contacts Recently Updated
Is there a way to search for Contacts recently updated (within past week or month) by a specific user?
I would like to do this by going to Search > Contacts and then entering a specific user and date into the Additional Search Arguments field since the fields (last modified by and last modified date) do not exist on the search page.
I have tried several queries but neither work.
last_mod_by = 'itpamuser' AND last_mod_dt > StartAtTime(\'LAST_MONTH\')
last_mod_by = 'itpamuser' AND last_mod_dt > '07/01/2024'
last_mod_by = 'itpamuser' AND last_mod_dt > '07/01/2024 00:05:00'
thank you
TheKatherine
