Hey,
I was struggling with the search example from the readme and realised that it was because the example used in the search for a ticket uses the syntax for Zammad <=3.6 (state: new) and not the new one (state.name: new).
As in : https://user-docs.zammad.org/en/latest/advanced/search.html
If it's meant to be updated, I can open a PR 🤷♀️
Cheers
