Document Grabber error


I am trying to use Document Grabber to extract articles about albuterol, but I am getting the following error:

ERROR : KNIME-Worker-14-Document Grabber 4:1 : : Node : Document Grabber : 4:1 : Execute failed: Server returned HTTP response code: 502 for URL:,32949514,32949512,32948510,32947961,32939610,32937917,32933892,32933140,32928411,&retmode=xml&rettype=abstract#

What should I do?

Hi @Vincent_Pham -

What about just using the comma separated IDs of the documents of interest, like this:

This seemed to work for me, unless I’m missing some nuance of what you’re trying to do.

Alternatively, you could search for the term ‘albuterol’, but that returns >1000 different documents.

Thank you! I did not want over 1,000 articles, so I will use the document IDs of the albuterol articles I want.
