How to sort search serults

[piust]

Hello.

I am wondering if there is a way to sort the search result.
I tried to use the sintax of STAC-API Sort extension but the service answers with a 400 error.

Thank you.

Hi @piust, I had a look at your example and there are a few things that might need to be fixed:

• properties.published is not a default field in STAC. You can take a look at the created/updated field
• the sortby field should be an array of sort keys

I modified your example into a working query with sorting:

{
  "filter": {
    "op": "and",
    "args": [
      {
        "op": "and",
        "args": [
          {
            "op": "=",
            "args": [
              {
                "property": "properties.constellation"
              },
              "sentinel-2"
            ]
          }
        ]
      },
      {
        "op": ">=",
        "args": [
          {
            "property": "properties.updated"
          },
          {
            "timestamp": "2024-11-10T00:00:00.000Z"
          }
        ]
      }
    ]
  },
  "collections": [
    "sentinel-2-l2a"
  ],
  "fields": {
    "include": [
      "properties",
      "geometry",
      "type",
      "id",
      "bbox",
      "stac_version",
      "assets",
      "collection"
    ]
  },
  "limit": 100,
  "sortby": [
    {
      "field": "properties.updated",
      "direction": "desc"
    }
  ]
}

I hope this helps!
