  79. * demand. To be able to tell where the next offset starts the search uses
  80. * "cursors" which are a property of the last result entry. E.g. search results

  83. * offset approach as the offset moves as new data comes in. The cursor is
  84. * resistant to these changes and will still show results without overlaps or
  85. * gaps.
