My searches on Zotero desktop are not finding keywords located in the Extra box. I've searched Full Text with no luck, and I don't see any other way to search. Any ideas for solutions?
In looking in the forums, some images show a different search box than what I see. There's also a magnifying glass symbol indicating a search, which I don't see on the desktop version.
It sounds like you're looking on the website, where what you're trying to do isn't possible. You need to download (zotero.org/download, install, run, and sync Zotero to take advantage of most of its features (I understand that you say you're using the Desktop version, but what you describe definitely isn't it).
In the Advanced Search window, search in the “Extra” field. “Full Text” refers to the text of PDF attachments.
Title, Creator, Year
Full Text
Searching Full Text doesn't capture the keywords I'm looking for.
