GeoServer supports the use of CQL/OGC-FILTERS with coverages?

Dear List,
I see in the GeoServer docs that filters (CQL & OGC filters) are well supported for WMS and WFS.
But what about rasters served through WMS?
Does GS will support that kind of filtering?
If not, does SLD (raster symbolizer) support coordinate filters/confrontation?


Best regards

"Au contraire mon ami"..

My layer is an ImageMosaic raster.. In my geoserver demo page the Filtering field is disabled, and also if I try to get the image with a request of type:

http://localhost/geoserver/wms?
// I've tryed:
cql_Filter=BBOX(the_geom, 702061,111190,706159,114165)
cql_Filter=Ortofoto_index>10
cql_Filter=exclude

&WIDTH=438&
HEIGHT=550&
SRS=EPSG%3A21781&
LAYERS=istgeo%3AOrtofoto_index&
STYLES=&
FORMAT=image%2Fjpeg&
SERVICE=WMS&
VERSION=1.1.1&
REQUEST=GetMap&
EXCEPTIONS=application%2Fvnd.ogc.se_inimage&
BBOX=701380.2490234375,109692.3828125,706352.6611328125,115936.279296875

But GeoServer doen't make any difference between request with or w/o cql_filter parameter..

 So I repeat my question..

Does GeoServer does/will support filtering on ImageMosaic raster layers?
If not, does SLD (rasterSymbolizer) support filters/confrontation on coordinates?


Cheers

CQL filters are applied only to vector data.
Raster symbolizer does not allow for such filtering either
