I have run a PubMed query using the 'Document Grabber' node, and ten use the 'Document Data Extractor' node to attempt to extract some of the relevant data from the query results. Whilst most of the fields seem to be extracted OK, the Abstract field appears to only retrieve the title. Viewing the results in the Document Viewer node, the abstract is displayed fine there, so I suspect a bug in the document data extractor?
Also, are there plans to expand range of databases covered - the dropdown currently only has PubMed - what about e.g. PubChem?
