Querying is controlled via the mode parameter. Mode=query does a point query returning at most 1 result in one layer. Mode=nquery allows you to query multiple layers and return multiple results from either a point or a rect. MapServer looks at the various additional supplied parameters to decide whether to do a point or rect query.
For example, this url will drop a point through all queryable layers that have status DEFAULT (since I'm not explicitly turning anything on) http://mapserv.org/cgi-bin/mapserv?map=foo.map&mapxy=x+y&mode=nquery and this will do a bbox query: http://mapserv.org/cgi-bin/mapserv?map=foo.map&mapext=minx+miny+maxx+maxy&mode=nquery You can turn layers on with the layer or layers parameters and can restrict queries to one layer (if necessary) using qlayer. mode=query ~ queryByPoint with MS_SINGLE mode=nquery ~ queryByPoint with MS_MULTIPLE or queryByRect The qlayer parameter has the effect of running the query methods on a layerObj while without it you're running on the whole mapObj. Does this help?
