Hi,
I found a solution myself, writing it down here, so that somebody next could
find it.
{"limit": 1, "datetime": "2021-08-01T00:00:00Z/2022-12-01T23:59:59Z",
"collections": ["sentinel2_full_test"], "filter": {"op": "lte" , "args":
[{"property": "eo:cloud_cover"}, 10]}, "filter-lang": "cql2-json"}
.. has to be changed to
{"limit": 1, "datetime": "2021-08-01T00:00:00Z/2022-12-01T23:59:59Z",
"collections": ["sentinel2_full_test"], "filter": {"op": "<" , "args":
[{"property": "eo:cloud_cover"}, 10]}, "filter-lang": "cql2-json"}

Subject: [Geoserver-users] STAC filtering
Hi,
We have been testing GeoServer STAC and have got it mostly working:
http://86.50.229.158:8080/geoserver/ogc/stac/
The last minor problem is that search with a filter does not work, although
conformance page gives hope for that:
[ http://86.50.229.158:8080/geoserver/ogc/stac/conformance?f=text%2Fhtml |
http://86.50.229.158:8080/geoserver/ogc/stac/conformance?f=text%2Fhtml ]
Also collections Queryables page looks ok:
[
http://86.50.229.158:8080/geoserver/ogc/stac/collections/sentinel2_full_test/queryables
|
http://86.50.229.158:8080/geoserver/ogc/stac/collections/sentinel2_full_test/queryables
]
We have been testing mostly with pystac-client Python package, but the same
error is given by API request:
[
http://86.50.229.158:8080/geoserver/ogc/stac/search?f=application%2Fgeo%2Bjson
|
http://86.50.229.158:8080/geoserver/ogc/stac/search?f=application%2Fgeo%2Bjson
]
POST
{"limit": 1, "datetime": "2021-08-01T00:00:00Z/2022-12-01T23:59:59Z",
"collections": ["sentinel2_full_test"], "filter": {"op": "lte", "args":
[{"property": "eo:cloud_cover"}, 10]}, "filter-lang": "cql2-json"}
The error in the log is:

We have been removing fields from default database and from default templates,
but basic search is working ok, for example POST with
{"limit": 1, "datetime": "2021-08-01T00:00:00Z/2022-12-01T23:59:59Z",
"collections": ["sentinel2_full_test"], "intersects": {"type": "Point",
"coordinates": [25.6, 65.1]}}
So I am not sure where to look next.. Any ideas?
In Global Queryables we have at the moment:
id, geometry, eo:cloud_cover
Not actually sure, what should be used here, DB field names or STAC attribute
names or some EO-Search names.
**
A comment about EO-search packaging, it seems that gt-cql-json-28.0.jar is
required by 2.22.0 GeoServer, but that .jar is currently not included in
GeoServer packages, so I added it manually added from GeoTools
https://sourceforge.net/projects/geotools/files/GeoTools%2028%20Releases/28.0/
