- $ XAPIAN_PREFER_CHERT=1 notmuch new
-
-I did not need the `XAPIAN_PREFER_CHERT`, but am not sure whether
-there are situations making it necessary (certain compile-time options
-to xapian?). This note is just here to be extended or removed by
-somebody more knowledgeable.
-
-After the initial import it is definitely not necessary to define
-`XAPIAN_PREFER_CHERT` for subsequent calls of `notmuch new`.
