I should know this, but why, when I do a search, are some items presented black and others greyed-out? They all seem to contain the word I'm searching for.
Really?? I'll check that but none of the parent items included the search term ('annular') and at least the pdf I checked, where the parent item was greyed, did ... hmmm.
I am seeing all my items in My Library, select one tag, see the items that have this tag, but then gradually Zotero is showing me more and more items that does not have this tag, and these items are grey.
Sibling items are items attached to the same parent item. So if a search finds a note attached to an item that also has an attached file, the attached file is the "sibling" of the found note and will be shown greyed out.

What does this mean?
