Alert Composer: Filter to exclude specific learning items

Content

Hello,

Anyone have any recommendations for a filter to exclude multiple learning items?  

We can only get it to work for a single learning item and need to prevent alerts for specific OLC Numbers.

Here's what I've tried:

${learningItemNumber}<>'OLC3129356' OR ${learningItemNumber} <>'OLC3130220'

Thanks in advance!
