• The docstring for search_data includes undocumented parameter cloud_hosted in its example.
• downloadable parameter is not documented.
• I think there are others, but I don't have time to be exhaustive at the moment :)

Currently, kwargs are passed from search_data to a DataGranules object's parameters method, which also accepts kwargs. The possible keys are fixed by the methods on DataGranules, and populated dynamically by matching keys to method names.

The same technique is used for both data & dataset search functions.

However, the interface is untyped and the documentation is generated from a hand-maintained docstring. I feel we should move towards fully typing the interface and generating the docs from the annotations. Python's type system feels like a toy at times like this. How do we ensure that a DataGranules method exists for each parameter on the search_data interface? Maybe we should instead collect the parameter methods in a dict? Just thinking out loud.
