Summary

In some instances, operator = Empty is broken when combining with other condition, for example: JQL resolutiondate = EMPTY OR resolutiondate >= -30d is returning incorrect results. The results will be less than JQL resolutiondate = EMPTY

Steps to Reproduce

1. Go to Issue Navigator
2. Type the following JQL: resolutiondate = empty
   Please take note the number of records returned.
3. Next, combine the JQL above with other condition, for example: resolutiondate = empty OR resolutiondate >= "-30d"
   Please take note the number of records returned.

Expected Results

The results will be the OR of both conditions

Actual Results

The number of records that is returned is actually less than the JQL resolutiondate = empty alone. In this case: resolutiondate = empty OR resolutiondate >= "-30d" returns less number of records than resolutiondate = empty

Workaround

Modify = empty to use is empty instead

Additional Notes

resolutiondate = EMPTY works!
resolutiondate is EMPTY works!
resolutiondate is EMPTY OR resolutiondate >= -30d works!
resolutiondate = EMPTY OR resolutiondate >= -30d returns incorrect results!
