[Mapserver-users] qstring - multiple values

[Zamil Murji]

Just out of curiosity, what would be the equivalent logical expression.

BTW, I am in favor of implementing something like this.

Thanks
Zamil

I would certainly like that as a feature request. Lots of maps out there 
with discrete or enumerative map items. I guess it could also be 
implemented faster than the equivalent logical expression.
