Update the docs to show how to use the collection-search-only STAC API (instead of the custom STAC + CMR API).

Line #6.            "bbox": ",".join(str(coord) for coord in finland_bbox),

might be nice to print the syntax of a good bbox for people to see as they try to make their own.

I haven't tried all the code yet, just reviewed the text and overall document.
We're going to need to include changes to https://docs.maap-project.org/en/latest/technical_tutorials/searching.html
We want to make this method of searching the 1st option people use.

@wildintellect thanks for the structural feedback - I added the guide to the web app and moved pystac-client to the top of the API section.

Now we just need someone to have time to test the code ... @HarshiniGirish ?

@hrodmn @wildintellect I’m seeing different behavior between MAAP Hub and MAAP ADE. The same notebook runs on Hub, but on ADE it fails in the collection search cell with AttributeError: 'Client' object has no attribute 'collection_search'

That's probably a pystac-client version difference error? @hrodmn can confirm. But does leave the question of the validity of these instructions while on the ADE and if these docs then need to move to the Hub branch?

Since the ADE image has pystac-client pinned to 0.6.x you have to upgrade pystac-client to a more recent version to make it work. We can leave it as-is and stick this in the hub branch or I can add a note at the top declaring the version requirement and showing how to install it on the ADE.
