Search papers in Duaer

What Papers returns

Papers in the Duaer data market searches published papers. Each item has source, title, url, and summary. The price is 1 credit per successful search.

Add the node from the Duaer Data category by choosing Papers. The catalog entry is on Use the Duaer data market. Opening the market or copying the skill does not charge credits and does not run a search.

Use Duaer Data on the canvas

1. Open the node creator, select Duaer Data, then Papers — or search for Duaer Data / paper and connect the node after the previous node.
2. Leave Operation on Papers.
3. Fill at least one search field: Words, Title, Abstract, Author, Year From / Year To (0 means any), or Type, Open Access, Citations, Language, DOI, Journal, Institution, Topic.
4. Sort defaults to relevance; optionally Most cited. Limit defaults to 10, max 20.
5. Select Execute step.

A successful search uses 1 credit. An empty search, a failed search, or no remaining credits uses 0. When this node is the deliverable of a production run, items land in the data pool.

Duaer stamps a loopback URL and bearer onto the node at run time so it hits the same charged route. You do not enter a key in the panel.
