Magic Wand not importing tags (keywords) from Elsevier articles (but Connector does)
It appears that the Magic Wand does not import tags (keywords) from some Elsevier articles. Since adding the same articles via the Zotero Connector in Chrome *does* import the tags (keywords), I suspect that the issue lies with the Magic Wand, rather than with the data source.
Example: the article at https://doi.org/10.1016/j.solener.2004.05.005 has three keywords. Importing this article by supplying its DOI URL to the Magic Wand yields no tags, while importing the same article via the Zotero Connector in Chrome converts the three keywords to three tags.
I'm running Zotero 5.0.84 under Win10Pro.

A future version of Zotero will likely load the webpage associated with the DOI and augment the metadata that way, but for now you'd have to save from the publisher page to get the tags.
