[j08lue]

The semantic search bot adds some CQL2 filters to the query that

payload:

{"return_search_params_only":true,"query":"cloud-free sentinel-2 over london may 2025","limit":10}

response:

{
    "results": {
        "items": null,
        "search_params": {
            "max_items": 20,
            "collections": [
                "sentinel-2-l2a",
                "sentinel-2-c1-l2a",
                "sentinel-2-pre-c1-l2a",
                "sentinel-2-l1c"
            ],
            "datetime": "2025-05-01/2025-05-31",
            "filter": {
                "op": "and",
                "args": [
                    {
                        "op": "lte",
                        "args": [
                            {
                                "property": "eo:cloud_cover"
                            },
                            10
                        ]
                    }
                ]
            },
            "intersects": {
               ...

passed to the STAC API when I submit the query:

{"datetime":"2025-05-01T00:00:00.000Z/2025-05-31T00:00:00.000Z","intersects":{"type":"MultiPolygon","coordinates":[...],"limit":20,"collections":["sentinel-2-l2a","sentinel-2-c1-l2a","sentinel-2-pre-c1-l2a","sentinel-2-l1c"]}

Note that the filter objects are missing.
