Select logs with a oor is the filter not working in Forticloud

Hello,

I'm use a fotigate 40F in version 6.4.3. I can consult the logs in forticloud but when I do a filter with "or" command I'ts working fine in the memory but not in the forticloud

If I use a request without the command "or" its working fine in the memory and in the forticloud

Do you know if other users have got the same issue ?

Do you think, this a bug or an issue in the configuration ?

Thans
