However, starting a term with a capital letter suppresses stemming (because it suggests that it's a name, which you wouldn't want to modify), so your last query matches only the term "debian". This is probably documented somewhere, though I don't know where. > Where can I read more about this? (except the source :) Most of this is in the Xapian query syntax document you found. Really we ought to beef-up Notmuch's query syntax documentation.
