* Mail document
* -------------

+ * A ghost mail document is like a mail document, but where we don't

+ *
+ * A ghost mail document has type: ghost; id and thread fields that
+ * are identical to the mail document fields; and a MESSAGE_ID value.
+ *
* Directory document
* ------------------
* A directory document is used by a client of the notmuch library to
* generated is 1 and the value will be
* incremented for each thread ID.
*
+ * Obsolete metadata
+ * -----------------
+ *
+ * If ! NOTMUCH_FEATURE_GHOSTS, there are no ghost mail documents.
+ * Instead, the database has the following additional database
+ * metadata:
+ *
* thread_id_* A pre-allocated thread ID for a particular
* message. This is actually an arbitrarily large
* family of metadata name. Any particular name is
