Hi, I'm trying to take advantage of the tag:replied to give higher priority to emails sent to very busy lists but it seems that it's not returning the results that I am expecting. $ notmuch search tag:unread AND from:lydia thread:000000000001a791 Today 17:20 [1/10] Lydia | Wael Nasreddine; ... (inbox replied unread work) $ notmuch search tag:unread AND tag:replied As you can see in the snippet above, I do have an email that has both tags *unread* and *replied* but when I query for both, it does not find that email (it does not find anything for that matters). What am I doing wrong? Thanks, Wael -- Wael Nasreddine | SRE at Google | wael.nasreddine@gmail.com | (650) 735-1773
