Hi Angel
If I understand correctly, you want to search automatically after paste some text into the autocomplete. Right? and it's a global behaviour change, not only into authorship field for publications. Right?
I think that is possible add this behaviour and we can change it in the next update (6.2)
Note: Maybe is necessary to create a topic with new things or changes to do for the next versions and call to others to do annotations... something as "things to add/change for the 6.3" (version 6.2 is close to be released). what do you think?
Best
