         When indexing an encrypted e-mail message, if this variable is
         set to ``true``, notmuch will try to decrypt the message and
-        index the cleartext.  If ``auto``, it will try to index the
-        cleartext if a stashed session key is already known for the message,
-        but will not try to access your secret keys.  Use ``false`` to
-        avoid decrypting even when a session key is already known.
-
-        Be aware that the notmuch index is likely sufficient to
-        reconstruct the cleartext of the message itself, so please
-        ensure that the notmuch message index is adequately protected.
-        DO NOT USE ``index.decrypt=true`` without considering the
-        security of your index.
+        index the cleartext, stashing a copy of any discovered session
+        keys for the message.  If ``auto``, it will try to index the
+        cleartext if a stashed session key is already known for the message
+        (e.g. from a previous copy), but will not try to access your
+        secret keys.  Use ``false`` to avoid decrypting even when a
+        stashed session key is already present.
+
+        ``nostash`` is the same as ``true`` except that it will not
+        stash newly-discovered session keys in the database.
+
+        Be aware that the notmuch index is likely sufficient (and a
+        stashed session key is certainly sufficient) to reconstruct
+        the cleartext of the message itself, so please ensure that the
+        notmuch message index is adequately protected.  DO NOT USE
+        ``index.decrypt=true`` or ``index.decrypt=nostash`` without
