Hi Francesco,
I don't think that the authority field is relevant for your use case.
The authority field is used to track the id of the author as defined by the
external system that "own" the controlled list.
In your scenario you only need to help the user to input the data using an
autocomplete that suggest from the list of already usered values.
I suggest to you to take a look to the browse system that already store (if
configurated in this way) an index for the author fields (dc.contributor.*).
Please note that currently the browse system only work on dbms storage (oracle
or postgresql) but I have proposed an improvements for dspace 3 to support
browse via solr JIRA DS-1218.
Finally you could be interested in an additional module dspace-cris that allow
you to manage inside dspace author profiles and use these as authority list in
submission.
Please find some initial information at

Hope this help,

You right, can't retrieve authority confidence with solr! only names.
I'll try to implement a plugin class with that query. But still
wondering about nobody ask for this kind of implementation..
thank you again
