@dvcrn After update, it works ok.
1. Search in Alfred: "ds <item>"
2. [Enter] on the found item in the Alfred list
–> The item opens in DevonThink
Remarks:
1. The search does not ignore diacritics. If there is "Ramón" in DevonThink, searching for "ds ramon" in Alfred does not reveal the "Ramón" DT item.
2. It searches also in Trash which I think is not handy.
Anyway, nice workflow!
