JQL query to get all ticket except resolved ticket before a date

Julien Nivet_48ygtx

Hi, 

I would like to build a query. List all tickets (whatever the status) and removing tickets before a specific date. 

I've tried this :

project = XYZ AND NOT (resolved <= 2020-12-31)

But it is also filtering all the issue not resolved. I would like to get everything except those resolved before 2020-12-31

Many thanks for your help, 

Dirk Ronsmans

i'm thinking something along the lines of

project =XYZ AND ( resolutiondate <= 2020-12-31 OR resolutiondate IS EMPTY)

This will give you all tickets unless those resolve before that date. if they are not yet resolved or before that date they will be filtered out
