/* Here's the current schema for our database (for NOTMUCH_DATABASE_VERSION):
*
- * We currently have two different types of documents (mail and
- * directory) and also some metadata.
+ * We currently have three different types of documents (mail, ghost,
+ * and directory) and also some metadata.
*
* Mail document
* -------------
*
* SUBJECT: The value of the "Subject" header
*
+ * LAST_MOD: The revision number as of the last tag or
+ * filename change.
+ *
* In addition, terms from the content of the message are added with
* "from", "to", "attachment", and "subject" prefixes for use by the
* user in searching. Similarly, terms from the path of the mail
*
* The data portion of a mail document is empty.
*
+ * Ghost mail document [if NOTMUCH_FEATURE_GHOSTS]
+ * -----------------------------------------------
+ * A ghost mail document is like a mail document, but where we don't
+ * have the message content. These are used to track thread reference
+ * information for messages we haven't received.
+ *
+ * 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
{ "from", "XFROM" },
{ "to", "XTO" },
{ "attachment", "XATTACHMENT" },
