AW: [mapserver-users] Filter elements on multiple layers

[leene]

Hi,
thank you Alex. I found the solution in the same thread, you've posted: 
http://www.mail-archive.com/mapserver-users@lists.osgeo.org/msg10704.html

I must add the <BBOX> of the whole map to the filter and I'll get all matches.

Regards,
Cathleen

Hmm, I just tested this--it seems that you'd always get features where
the envelopes for the results from each layer spatially intersect,
(i.e. anything within the blue rectangle of your image).
