Custom query for filter in Get Customer Data action

[Ed_Graham]

I need to filter the list of customers returned by the Get customer data action according to whether a customer has a specific tag.  I have tried the syntax

query=tags:EdTest

and all variations that I can think of; but nothing filters the list successfully.

According to the documentation on filter parameters shown here, I ought to be able to do this somehow.  What am I doing wrong?

Can't you explain the solution here so that everyone else can benefit as well?

Thank you for your reply.  As per my original question, I'm interested in scenario #3.  In particular, I want to know how to craft a custom query for a filter in the Get Customer Data action.  Please see the screenshot(s) in my question above for more details.

Thank you for your reply.  However, as explained in my original question, I have already tried to adjust the filters directly in the action settings - but without success.  Please see the first screenshot in my question above.  I have tried tag:Edtest, tags:Edtest, query=tag:Edtest and query=tags:Edtest in the action settings; but none of these filters my list of customers according to the presence of the tag "EdTest", which is my aim.

I finally cracked it!  Turns out I was wrong in my last post: I had tried tag=EdTest but not tag:EdTest, which turned out to be the right answer!
