Here's a code fragment from some working code that does much like
that.

  name = argstr[1..index(argstr, " ") - 1];
  object = argstr[index(argstr, " ") + 1..length(argstr)];
  who = player.location:match_object(name);
  "Remove this next 2 lines if you only want to match objects";
  "in the current location";
  if (!valid(who))
    who = $string_utils:match_player(name);
  endif
  if (valid(who))
    "You found a player";
    "Do something similar for the object";
  endif

    /t
