* We currently have three different types of documents (mail, ghost,
* and directory) and also some metadata.
*
+ * There are two kinds of prefixes used in notmuch. There are the
+ * human friendly 'prefix names' like "thread:", which are also used
+ * in the query parser, and the actual prefix terms in the database
+ * (e.g. "G"). The correspondence is maintained in the file scope data
+ * structure 'prefix_table'.
+ *
* Mail document
* -------------
* A mail document is associated with a particular email message. It
- * is stored in one or more files on disk (though only one has its
- * content indexed) and is uniquely identified by its "id" field
- * (which is generally the message ID). It is indexed with the
- * following prefixed terms which the database uses to construct
- * threads, etc.:
+ * is stored in one or more files on disk and is uniquely identified
+ * by its "id" field (which is generally the message ID). It is
+ * indexed with the following prefixed terms which the database uses
+ * to construct threads, etc.:
*
* Single terms of given prefix:
*
* 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
- * message are added with "folder" and "path" prefixes. But the
- * database doesn't really care itself about any of these.
+ * The prefixed terms described above are also searchable without an
+ * explicit field name, but as of notmuch 0.29 this is due to
+ * query-parser setup, not extra terms in the database. In addition,
+ * terms from the content of the message are added without a prefix
+ * for use by the user in searching. Note that the prefix name "body"
+ * is used to refer to the empty prefix string in the database.
+ *
+ * The path of the containing folder is added with the "folder" prefix
+ * (see _notmuch_message_add_folder_terms). Sub-paths of the the path
+ * of the mail message are added with the "path" prefix.
*
* The data portion of a mail document is empty.
