this is not working ---- collections response is now sorting by lastModified date. about api HOT 2 CLOSED

"message": "Error page size + offset must be less than maxoffset: 10000"

from api.

@ganeshkharad2 - The API has a 10,000 item limit for the collections request, so if your count is higher than that, you should consider splitting your request range using both startDate and endDate.

https://github.com/usgpo/api#collection-update

The collections response is sorted by each package's lastModified value, starting with the newest first.

so, you could use:

https://api.govinfo.gov/collections/CHRG/1990-01-01T00:00:00Z/?offset=9899&pageSize=100&api_key=DEMO_KEY
to get the last value available there. The last item available for that request would be:

{
	"packageId": "CHRG-113hhrg86796",
	"lastModified": "2018-07-30T19:11:28Z",
	"packageLink": "https://api.govinfo.gov/packages/CHRG-113hhrg86796/summary",
	"docClass": "HHRG",
	"title": "Changes to the Height Act: Shaping Washington, D.c., for the Future, Part II",
	"congress": "113"
}

What I would recommend would be to construct the request to start with that one - you may need to slightly adjust to get only 10k results, as multiple packages may be published at the same time.

https://api.govinfo.gov/collections/CHRG/2018-07-30T19:12:28Z/?offset=0&pageSize=100&api_key=DEMO_KEY

which has 9831 results.

You could then use the startDate from the above as the endDate for a follow-on request.

https://api.govinfo.gov/collections/CHRG/2018-06-01T00:00:00Z/2018-07-30T19:12:28Z/?offset=0&pageSize=100&api_key=DEMO_KEY

Then you could do a further set of requests until you get to the total number of results. Based on the base collections request, there are 27858 total packages:

https://api.govinfo.gov/collections?api_key=DEMO_KEY

{
	"collectionCode": "CHRG",
	"collectionName": "Congressional Hearings",
	"packageCount": 27858,
	"granuleCount": 33
},

Alternatively, if you want to retrieve the full set of CHRG, you could use our sitemaps to identify all packages currently in the system, using the packageid as identified in the <loc> values.
