Today we noticed that keywords can't be searched as prefixed terms. Or that's what it looks like anyway. I tested and, or, and not. ╰─% NOTMUCH_DEBUG_QUERY=y notmuch search 'subject:"and"' Query string is: subject:"and" notmuch search: A Xapian exception occurred A Xapian exception occurred parsing query: Syntax: <expression> AND <expression> Query string was: subject:"and" ╰─% NOTMUCH_DEBUG_QUERY=y notmuch search 'subject:"or"' Query string is: subject:"or" notmuch search: A Xapian exception occurred A Xapian exception occurred parsing query: Syntax: <expression> OR <expression> Query string was: subject:"or" ╰─% NOTMUCH_DEBUG_QUERY=y notmuch search 'subject:"not"' Query string is: subject:"not" notmuch search: A Xapian exception occurred A Xapian exception occurred parsing query: Syntax: <expression> NOT <expression> Query string was: subject:"not" Interestingly, putting space around the operator seems to be a workaround. Something about turning on phrase parsing maybe? ╰─% NOTMUCH_DEBUG_QUERY=y notmuch count 'subject:" not "' Query string is: subject:" not " Exclude query is: Query((((Kspam OR Kdeleted) OR Kmuted) OR Kbad-address)) Final query is: Query(((Tmail AND 0 * XSUBJECTnot@1) AND_NOT (((Kspam OR Kdeleted) OR Kmuted) OR Kbad-address))) 9927 _______________________________________________ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
