`notmuch help search-terms` currently states: "In addition to individual terms, multiple terms can be combined with Boolean operators ("and", "or", "not", etc.).". I would like to replace the "etc" with a full list and document the operator precedence. In lib/notmuch.h for notmuch_query_create I found a pointer to xapian docs [2], which states that AND takes precedence over OR, but nothing for NOT and XOR. Through playing with `notmuch tag` and `notmuch search --output=messages` I found: Complete list of boolean operators in order of precedence: - NOT - AND - XOR - OR Is this correct? If yes, I would extend the manpage accordingly.
