Hey there...!
Most certainly I'm making something wrong here, but I can't make this module work for me.
Installed it as usual in my local machine (ddev), and configured it to work along two fields:
a taxonomy field, with terms from numbers 1 to 11
and a date field.
Created several nodes repeating both inputs.
No joy.
Changed the taxonomy field with a integer number field, again numbers 1 to 11.
Several nodes later repeating both inputs, no joy.
Changed the date field with another integer number field, which served as a date, and left intact the other integer.
A few nodes later, also repeating both inputs and nothing.
Then gave up with the combination values and checked as the unique field only the faux date field, created a few nodes with the same integer.
Nothing.
Can somebody please point me in the right direction...?
Thanks
Warm regards from sunny México.

Sorry, the module doesn't support checking of overlapped date (or time) ranges. It can only compare exact values.
