I know it's a bit late for comments on this, but ...

After digesting the proposed search points for a while I have one
comment.  In my opinion, it would make sense to have the "role" as a
modifier to the "name" search point.  It could just be me, but the
proposed author search syntax seems unworkable.  Since both "name" and
"role" are top level search points, one has to contort the meaning of
the search to link the role and name in some way.  Also, searching
based on role as a primary search point doesn't seem to provide much
utility -- would you search for all materials that have an
illustrator?  I guess you could, but that could be done by matching
any name with a role of 'illustrator'.

My proposition would be to add a role modifier to the name index, in
addition to type, part and authority, such that queries would be
expressed in this way:

mods.name/type=personal/part=family/authority=lcauth/role=author

Other than that minor objection, which I plan to add as a local
extension, I think it is a nearly perfect expression of the useful
search points in MODS.

Thanks for all the hard work on this!
