Thanks for the response, Jens. I'm not sure what caused the problem,  
as I hadn't made any changes to the server, but I looked into Dovecot  
issues (the IMAP software on my server) and I found one related to the  
FTS (full text search indexing) that solved the problem:

doveadm fts rescan -u user at domain

I ran that for each email account that was exhibiting the problem  
(which included only one of the domains on my server) and my searches  
are back to normal.
