I'm trying to use cmr-stac to search collections at NSIDC. However, the following code only returns 10 datasets. It appears that their is a limit on the dataset. I get a similar result for PODAAC collections. Is there a work around for this or is it a bug?

from pystac_client import Client
nsidc_cat = Client.open('https://cmr.earthdata.nasa.gov/stac/NSIDC_ECS')
nsidc_cat.get_links()

@andypbarrett you can increase the 'limit' for returned links, because the default is just 10 nsidc_cat = Client.open('https://cmr.earthdata.nasa.gov/stac/NSIDC_ECS?limit=50')
