In-library searching not returning records
Recently I have had a few instances where I've looked for a record in my Zotero library, e.., by author name etc. (desktop) and it appears not to exist. Looking for titles, keywords etc doesn't help. But when I am in Word and insert a citation using the plug-in, the reference is found. In other words, it IS in the library, but doesn't show up when I look for it. These are not new records (i.e., unlikely to be a sync issue), but references I have had in my library for years. Any ideas?
