Criteria for item to appear in Learning Search for users

[sud1]

Hi,

I would like to understand the criteria for item to appear in Learning Search for users i.e.

1) if an user has to view a Item in myLearning -> Search then that user and Item has to be in the same domain?, then only will it be visible?

2) Or both Item's and User's Library should match?

Is 1 Mandatory or 2 is mandatory or both?

Thanks
Sud
