The **from:** prefix is used to match the name or address of the sender
of an email message.
Each timestamp is a number representing the number of seconds since
1970-01-01 00:00:00 UTC.
+The **lastmod:** prefix can be used to restrict the result by the
+database revision number of when messages were last modified (tags
+were added/removed or filenames changed). This is usually used in
+conjunction with the **--uuid** argument to **notmuch search**
+to find messages that have changed since an earlier query.
