# Search STAC items with simple filtering.

`GET /search`

## Request

- Base URL: `https://geoservice.dlr.de/eoc/ogc/stac/v1`
- URL: `https://geoservice.dlr.de/eoc/ogc/stac/v1/search`
- Auth: none declared
- TypeScript: <https://skmtc.dev/dlr/apis/eoc-eo-products-service/docs/search/get.ts> (a function with typed inputs; its response is checked against the schema)

Retrieve Items matching filters. Intended as a shorthand API for simple
queries.

## Query parameters

- `bbox` number[]
- `datetime` string
- `limit` integer
- `ids` string[]: Array of Item ids to return. All other filter parameters that further restrict the number of search results are ignored
- `collections` string[]: Array of Collection IDs to include in the search for items. Only Items in one of the provided Collections will be searched.
- `sortby` string
- `fields` string
- `query` string

## Response `200`

A feature collection.

- ItemCollection: A GeoJSON FeatureCollection augmented with foreign members that contain values relevant to a STAC entity
  - `type` 'FeatureCollection', required
  - `features` Item[], required
    - `stac_version` string, required
    - `stac_extensions` union[]
      - union
        - string, uri
        - string
    - `id` string, required: Provider identifier, a unique ID, potentially a link to a file.
    - `bbox` number[], required: Only features that have a geometry that intersects the bounding box are selected. The bounding box is provided as four or six numbers, depending on whether the coordinate reference system includes a vertical axis (elevation or depth): * Lower left corner, coordinate axis 1 * Lower left corner, coordinate axis 2 * Lower left corner, coordinate axis 3 (optional) * Upper right corner, coordinate axis 1 * Upper right corner, coordinate axis 2 * Upper right corner, coordinate axis 3 (optional) The coordinate reference system of the values is WGS84 longitude/latitude (http://www.opengis.net/def/crs/OGC/1.3/CRS84) unless a different coordinate reference system is specified in the parameter `bbox-crs`. For WGS84 longitude/latitude the values are in most cases the sequence of minimum longitude, minimum latitude, maximum longitude and maximum latitude. However, in cases where the box spans the antimeridian the first value (west-most box edge) is larger than the third value (east-most box edge). If a feature has multiple spatial geometry properties, it is the decision of the server whether only a single spatial geometry property is used to determine the extent or all relevant geometries. Example: The bounding box of the New Zealand Exclusive Economic Zone in WGS 84 (from 160.6°E to 170°W and from 55.95°S to 25.89°S) would be represented in JSON as `[160.6, -55.95, -170, -25.89]` and in a query as `bbox=160.6,-55.95,-170,-25.89`.

It is formatted according to [RFC 3339, section 5.6](https://tools.ietf.org/html/rfc3339#section-5.6). `null` is allowed, but requires `start_datetime` and `end_datetime` from common metadata to be set.
