Valid prefixes for use with the find command are not provided in the UG.
Definition of prefix is also not provided.
Recommendation:
Put a list of valid prefixes under the command definition so the user will know what options they have. Could also refer users to edit command or add command to see what prefixes and fields they can search for.
E.g.
To search by name: find n/NAME
To search by tag: find t/TAG
etc.
