Hi, I've been consistently getting an error of this form: andy@andy-x200:~/work/talks/2017/icps$ notmuch new Processed 230 total files in 7s (29 files/sec.). Added 212 new messages to the database. Removed 85 messages. Detected 18 file renames. Error: A Xapian exception occurred flushing database: Value in posting list too large. ...and it seems that, since I've been getting this error, new emails are not reliably being found by, for example M-x notmuch in emacs. Can anyone help? Best Andy Wills Psychology Plymouth University, UK -
