Search STAC items in a collection.
GET/collections/:collectionId/items
The same query parameters may be used as those in the /search endpoint, except for "collections" since the collection to search is part of the URL path.
For authorization this method requires the use of a valid bearer token.

Bounding box in format "west,south,east,north" in WGS84 decimal degrees. When performing a spatial search specify either of the parameters "bbox" of "intesects", but not both.
Date range filter in format "start-date/end-date" or "exact-datetime"
Comma-separated list of STAC item IDs to return. The items returned are still subject to whatever other search filters are specified.
GeoJSON geometry to search by. Only STAC items whose geometries intersect this geometry are selected. When performing a spatial search specify either of the parameters "bbox" of "intesects", but not both.
A cql2-text filter expression for filtering items. You can filter on any property inside a STAC item's "properties" object.
While STAC items have a "datetime" property you should use the search operation's "datetime" parameter for searching by it, and not use the "filter" parameter for searching by datetime.
Example: eo:cloud_cover < 20
Example: eo:off_nadir < 10 and eo:sun_azimuth < 50
(Deprecated in favor of filter) SQL-style WHERE clause for filtering STAC items by properties. You can filter on any property inside a STAC item's "properties" object.
While STAC items have a "datetime" property you should use the search operation's "datetime" parameter for searching by it, and not use the "where" parameter for searching by datetime.
Example: eo:cloud_cover < 20
Example: eo:off_nadir < 10 and eo:sun_azimuth < 50
An array of property names, prefixed by either "+" for ascending or "-" for descending.
If no prefix is provided, "+" is assumed.
Currently only two properties are supported: datetime
and id
.
Example: id
Example: -id
Example: datetime
Example: -datetime
(Deprecated in favor of sortby) SQL-style ORDER BY clause. The only properties results can be ordered by are "id" and "datetime". You can use ASC and DESC modifiers on each column. If not specified then orderby defaults to "datetime DESC, id ASC".
Example: id
Example: id DESC
Example: datetime
Example: datetime DESC
Maximum number of items to return
Page number to retrieve. First page is numbered 1.

Possible values: >= 4
, <= 6
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):
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.
Possible values: [Feature
