# Search STAC items with full-featured filtering.

`POST /search`

Retrieve items matching filters. Intended as the standard, full-featured query API.

## Request body

- SearchBody — The search criteria
  - `query` Query — Define which properties to query and the operations to apply
  - `bbox` number[] — Only features that have a geometry that intersects the bounding box are selected. The bounding box is provided as four numbers: * Lower left corner, coordinate axis 1 * Lower left corner, coordinate axis 2 * Upper right corner, coordinate axis 1 * Upper right corner, coordinate axis 2 The coordinate reference system of the values is WGS84 longitude/latitude (http://www.opengis.net/def/crs/OGC/1.3/CRS84). 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). Example: The bounding box of Switzerland in WGS 84 (from 5.96°E to 10.49°E and from 45.82°N to 47.81°N) would be represented in JSON as `[5.96, 45.82, 10.49, 47.81]` and in a query as `bbox=5.96,45.82,10.49,47.81`."
  - `datetime` string — Either a date-time or an interval, open or closed. Date and time expressions adhere to RFC 3339. Open intervals are expressed using double-dots. Examples: * A date-time: "2018-02-12T23:20:50Z" * A closed interval: "2018-02-12T00:00:00Z/2018-03-18T12:31:12Z" * Open intervals: "2018-02-12T00:00:00Z/.." or "../2018-03-18T12:31:12Z" Only features that have a temporal property that intersects the value of `datetime` are selected. When used as URL query argument, the value must be correctly url-encoded.

  - `forecast:perturbed` boolean, nullable — Denotes whether the data corresponds to the control run (`false`) or perturbed runs (`true`). The property needs to be specified in both cases as no default value is specified and as such the meaning is "unknown" in case it's missing.

    - `stac_version` string, required
    - `stac_extensions` string[] — List of STAC extensions used by this feature. Properties that are not part of the default feature properties (`datetime`, `start_datetime`, `end_datetime`, `title`, `created`, `updated`) must be covered by one of the extensions listed here, otherwise the request is rejected. Additionally, when an extension is listed here, certain properties required by that extension must be present in the `properties` field.

    - `merge` boolean — This is only valid when the server is responding to `POST /search `request. If merge is true, the client is expected to merge the body value into the current request body before following the link. This avoids passing large post bodies back and forth when following links, particularly for navigating pages through the `POST /search` endpoint.

## Other responses

- `500` — The request was syntactically and semantically valid, but an error occurred while trying to act upon it
