What does "contains not" really do in the PLE?

I thought that “Contains Not” may be the same as “doesn’t contain”, but it is not working that way. In fact, I can’t tell what it does-it is just making all my tracks disappear. The manual doesn’t even mention “Contains Not” as an option:

Hi,

Could you share your PLE “script”, please?

Do you mean if you set the Filter Target to “Name”, or “Color Name”? Then is an opposite to “Contains”. So you can search for a sub-string in the name.

For example you have those tracks:

  • MIDI 01
  • Audio 01
  • Audio 02

If you set Name > Contains Not > 01, then Audio 02 is the result. If you set Name > Contains Not > Audio, then MIDI 01 is the result.
