  You could use the rows() method with any() to find this out:

  table.rows( { search: 'applied' } ).any();
  

  That would return true if there are results, false if not.

  Hi Allan, thanks for reply.
  I have this code:
  var oTable6 = $('#relations').DataTable();
  var select = oTable6
  .column( 0 ).search( '^'+inv+'$', true, false )
  .column( 1 ).search( '^'+yl+'$', true, false ).any();
  if( select == true)
  // something
  This does not work properly,select always is true
  Any idea about it?

  now I tried the following code and works fine
  var select = oTable6
  .column( 0 ).search( '^'+inv+'$', true, false )
  .column( 1 ).search( '^'+yl+'$', true, false );
  var info = select.page.info();
  if( info.recordsDisplay>0)
  $('.active')[index].checked = true;

  // something This does not work properly,select always is true Any idea about it?

  I'll need to draw() the table before the new search terms take effect.
