Quick filter to pull issues from one project into another project's board

Question

I am trying to write a quick filter to pull issues with a specific label in one project into a view in another project's board.   The syntax I'm using is "project = projectname AND labels = labelname."  The query works fine in the program wide search but not in an individual project board, where it produces no results.  Is this a permissions issue?  Thanks in advance for any help provided.

Quick filters are meant to reduce the amount of issues you see on the board, they can only show things that the board already brings as a result of the query associated to it. I would suggest that you include all the results in the board query and build the filter the other way around, meaning that if you select the filter, it must show all but the tickets from that project and label. That way if you deselect it, it's going to "add" those tickets on the board as well

Essentially the syntax for the board filter is as follows:

project in (project1, project2, project3)
