Hi Steve,
Thanks for your response.
I have already tried with supplying SRS name in query. Now tried again, but
results are still same.
Do you/someone know if I can somehow remove default spatial filter applied
while MapServer makes a call to PostGIS?
Thanks. Regards,
Kajod

Hi,
Greetings!
I hope this is a right platform to discussmy query regarding FILTER applied on
MapServer WFS.
I'm new in this area and exploring some featuresof MapServer. I want to use
GetFeature request of WFS to get features appliedon any location on map. I'm
using "MapServer version 7.0.4 (MS4W 3.2.1)"and trying to apply filter
"Contains" for it.
I can see two problems when it applies Filterquery on PostGIS:
1. It looks it adds an extradefault geospatial filter in it while making a
query to PostGIS. This defaultspatial filter is not stopping to return any
result from PostGIS. Is thereany way to exclude this default filter?
2. It seems Contains coordinatesare not transformed properly according to SRS
of data in PostGIS.
I've tries with different projection in mapfile and request message with no
success.
Supporting data to give your input on myqueries:

Similar WFS query to GeoServer works perfectly.
It would be very helpful if someone can helpme on it. Thanks a lot in advance.
