Thank you @deefree for sharing your CQL. It’s great to see you put together a complex CQL sequence that combines lemmas and tags. I tried it out and it works perfectly – here is the link for you: link.
The only thing I would recommend is changing the tag VVN.* since it only includes lexical verbs and not the verb be. I thought you might get more results since there’s an adjective following the verb. Instead, you can use the word been or become – see 66 instances here.
Finally, I am adding a screenshot to show you how to grab the link from SE – hope this helps:
