How to use a Query Map?

[Jean-Francois Doyon]

Hello,

So, I don't know if this should really be obvious to me or what, but I don't
seem to be having any luck figuring out how this feature works, possibly
caused by the fact that maybe I don't know exactly what it does ...

I am going based on the assumption this feature returns a map with the
features matching a query "highlighted" somehow?

Thing is we can't get it to return anything other than a blank map.

We've tried messing with a variety of CGI parameters, mapfile parameters,
etc ... without success.

If someone could share their successfull experience with this feature, it'd
be much appreciated.  Even better, if one of the developpers "in the know"
could detail the exact way it's supposed to work, I'll add it to the mapfile
reference ...

I've tried using things like a point with a huge buffer, or an extent that
covers the entire country, and no matter what, I just don't get anything
back!

Any help would be much appreciated ...

Thanks,
