🐛 Describe the bug

Reported by @scholes-ds

I think I have another example of products not returning when called with a collection call.

I’m trying to retrieve some information from the PDS API for ESA’s Trace Gas Orbiter (TGO).

This call only returns 68 products, while there are probably a minimum around 150k.
https://pds.mcp.nasa.gov/api/search/1/products/urn:esa:psa:em16_tgo_cas:data_calibrated/members

Here is a product that does not return as a member of the collection:

🕵️ Expected behavior

I expected all the products of the collection to be returned

@tloubrieu-jpl @alexdunnjpl is this part of the sweepers issue we have been seeing? it does not appear to have the parent_* metadata.

Given that it's PSA, it's safe to assume it's the result of incomplete processing - PSA back-processing is still ongoing

Suggest closing on that basis
