  One way is to assign a classname to each column you want to apply the search. This example is for text inputs but the same idea should work for select inputs.

  I found the case:
  take a look at "i" variable

       $('#mytable').DataTable( {
  
      initComplete: function () {
          this.api().columns().every( function (i) {
               (i == 2 || i == 4 || i == 5 || i == 6 )
              var column = this;
  
              var select = $('<select><option value=""></option></select>')
                  .appendTo( $(column.footer()).empty() )
                  .on( 'change', function () {
                      var val = $.fn.dataTable.util.escapeRegex(
                          $(this).val()
                      );
  
                      column
                          .search( val ? '^'+val+'$' : '', true, false )
                          .draw();
                  } );
  
              column.data().unique().sort().each( function ( d, j ) {
                  select.append( '<option value="'+d+'">'+d+'</option>' )
              } );
              }
          } );
      }
  } );
