I don't see this behaviour, so I don't think it's related to
org-contacts directly. One of the only thing it changes is the last mail
seen from a user, when used with Gnus. But a search does not do any
modification.

Sounds dangerous, but you can do it yourself anyhow.

The Emacs completion code is not that nice. But using only the first
address in EMAIL is doable.

This properties has been set to be used in `org-contacts' search.
Problem is the format in `org-contacts' is not changeable because the
way it is written in org.el itself. I've tried to enhance that (there's
a branch in the org repository about that) but it's really too much
work to me right now, so I abandonned for now that part.

That is what was planning, as I stated just above. But this is far from
doable right now and would require a major rewrite of some part of Org
to be done correctly.
