The filtering itself seems to be working since the number of matched features is correct.
But it’s only for filters DISJOINT and BEYOND the matched features are returned.
I’ve only tested with the example polygon from the cql_tutorial.html against the topp:states sample data so I can only know that it doesn’t work for DWITHIN, OVERLAPS, WITHIN and INTERSECTS since the others gives 0 matches.
DWITHIN:
[http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=DWITHIN(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040)),%2010,%20meters](http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=DWITHIN(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040)),%2010,%20meters))
Results in “totalFeatures”: 38,“features”: ,
OVERLAPS:
[http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=OVERLAPS(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040](http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=OVERLAPS(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040))))

WITHIN:
[http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=WITHIN(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040](http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=WITHIN(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040))))
Results in “totalFeatures”: 3, “features”: ,
INTERSECTS:
[http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=INTERSECTS(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040](http://localhost:8080/geoserver/topp/wfs?service=WFS&version=1.1.0&request=GetFeature&typeName=topp:states&outputFormat=application%2Fjson&CQL_FILTER=INTERSECTS(the_geom%2C%20POLYGON((-90%2040%2C%20-90%2045%2C%20-60%2045%2C%20-60%2040%2C%20-90%2040))))
Results in “totalFeatures”: 15,“features”: ,
If I swap to WFS version 1.0.0 the features are returned.
