SCAN UMODES +<modes>-<modes> [NO-LIST] [LIST] [GLOBAL]
            [LIST-MAX <number>] [MASK <nick!user@host>]

Searches the local server or network for users that have the
umodes given with + and do not have the umodes given with -.
NO-LIST disables the listing of matching users and only
shows the count. LIST enables the listing (default). GLOBAL
extends the search to the entire network instead of local
users only. LIST-MAX limits the listing of matching users to
the given amount. MASK causes only users matching the given
nick!user@host mask to be selected. Only the displayed host
is considered, not the IP address or real host behind
dynamic spoofs.

Network searches where a listing is given are operspy
commands.
