* Fixed a bug where moving a page would cause the following SQL error when
  updating the searchindex:
    UPDATE `Array` SET si_title='page 1' WHERE si_page='2910'
  from within function "SearchMySQL4::updateTitle". MySQL returned error
  "1146: Table 'HEAD.Array' doesn't exist (localhost)".
  The new query causes the following to be executed:
    UPDATE `searchindex` SET si_title='page 1' WHERE si_page='2909'

  the while move process)
