:: FTS ::
Syntax: FTS [range] <string> ["<board>"]

With this command a fulltext search over all mail or all mail of one
board can be started.
The bigger the mailbox and the slower the hardware the more time it takes!

Examples:  FTS tnc4            searches in all mail for string "tnc4"
           FTS 1-1000 kenwood  searches in the 1000 newest mails the
                               string "kenwood"
           FTS tm733 "technik" searches in all mail of board TECHNIK
                               the string "tm733"

Note: There is no difference in result when writing <string> in capital
      or small letters! If a board is defined, the range is ignored.
