Is the "contains" operator for queries not supported?

[NicholasPini]

In the stac-fastapi-pgstac GitHub repo I've found this comment in https://github.com/stac-utils/stac-fastapi-pgstac/blob/0357f130bfa202038b90bc9ffac5d0b9495cc564/stac_fastapi/pgstac/extensions/query.py#L22-L26 of the 5.0.0 version:

# TODO: These are defined in the spec but aren't currently implemented by the api
# startsWith = auto()
# endsWith = auto()
# contains = auto()
# in = auto()

Does this mean that stac-fastapi does not support these operators in queries? Is there any plan of supporting them, if this is the case? And if this is not the case, how can I use these features? Thank you.

Hi @NicholasPini, this the pgstac backend doesn't not implement it!

the stac-fastapi repo holds the CORE api code, but then it's up to each backend (pgstac / elastic search /...) to implement the search features. In stac-fastapi https://github.com/stac-utils/stac-fastapi/blob/main/stac_fastapi/extensions/stac_fastapi/extensions/core/query/request.py#L13-L37 we simply says that if the Query extension is enabled then the user should be able to pass a query= parameter (or body entry). Each backend can then define more precisely how they implement it.

it seems that the elastic search backend doesn't support the contains key as well https://github.com/stac-utils/stac-fastapi-elasticsearch-opensearch/blob/main/stac_fastapi/core/stac_fastapi/core/extensions/query.py#L33-L38
