What does the entityfield directive in the autocomplete map do?

[joebordes]

ah, sorry, that is for autocomplete. the idea is similar. As the documentation page indicates:

what information we should return: there will be one main entity identifier and possibly some additional fields to support the decision of what record to select

so you are indicating what is the main field we will show differentiated from the other secondary fields that support the decision.
