How to Limit a Select List Filter to Search Based on Exact Matches Instead of Substrings

I am working on a project where I have a select list with a filter functionality. Currently, the filter searches for substrings within the options, but I would like to modify it so that it only searches for exact matches based on the selected data.

For example, if the select list of column index 2 contains the options “New” , I saw rows with “New” and some rows with “NRND (Not Recommended for New Design)” , the filter should not return any results of “NRND (Not Recommended for New Design)” because is not an exact match for “New”, it was a substring of “New”.

columns = jQuery.parseJSON(data);
table.columns([38]).every(function (i) {     
  var column = this;
  $(column.header()).append("");
  var select = $('<select style="max-width:80px"><option value="">--</option</select>')
    .appendTo($(column.header()))
    .on('change', function ({
       filter_values[column.index()] =$(this).val();
       table.search(filter_values.toString() ? '' + filter_values.toString() + '' : '', true, false).draw();
    });
    select.append('<option value="0">0.X</option>');
    select.append('<option value="1">1.X</option>');
    select.append('<option value="2">2.X</option>');
    select.append('<option value="3">3.X</option>');
});

$(column.header()).append("<br>");
var select = $('<select style="max-width:80px"><option value="">--</option></select>')
  .appendTo($(column.header()))
  .on('change', function () {
    var selectedValue = $(this).val();
    filter_values[column.index()] = selectedValue;

    // Use the search method to filter and display the data
    table.search(filter_values.toString() ? '' + filter_values.toString() + '' : '', true, false).draw();
  });

  // Populate the select options
  columns[column.index()].forEach(function (d, j) {
    select.append('<option value="' + d + '">' + d + '</option>');
  }); 
});
