DOC: MAST - Limit number of products?

I've found that `Observations.get_product_list` takes a long time and returns huge lists for single observations (~300,000 entries that each have many columns). The documentation presently suggests that one should get that product list then filter it after the fact.

Is there any way to do the filtering before transferring the full metadata?

(this is related to several of the other recent issues about file sizes from MAST, especially https://github.com/astropy/astroquery/issues/2496, but I'm looking for a different workaround)

Start with the Observations.get_product_list entry point and read the current MAST documentation describing how product lists are retrieved and filtered. Review the discussion and the linked issue about MAST file sizes to determine whether pre-transfer filtering is supported. Done means the documented workflow accurately explains how to avoid transferring the full metadata, or clearly records that limitation.
