Advanced search with data-table

Question

I was wondering is there way to improve search in data table? I have a numeric column in a datatable. Is it possible to return back just the number being searched on?

So for example: 100 210 310 1

and if I search for 1 I want to show only :1 but not the others that contain 1

 jQuery(document).ready(function ($) {
    var db = $('#min-table').DataTable({
        "dom": '<"pull-left"f><"pull-right"l>tip',
        "bJQueryUI": true,
        "bSort": true,
        "bSearchable": true,
        "bPaginate": true,
        "lengthMenu": [[20, 35, 50, -1], [20, 35, 50, "All"]],
        "iDisplayLength": 20
    });

});

You can make use of datatable plugins to override some of the features. In your case, you can add your custom function to $.fn.dataTable.ext.search.push

$.fn.dataTable.ext.search.push(
    function( settings, data, dataIndex ) {
     const searchTerm = $("[type=search]").val();
     if(searchTerm){
       return data[3] === searchTerm
     }else{
       return true;
     }
    }
);

In the above code, I'm using a full text search on fourth column for each row. Row will be included or excluded based on the return value of the function (true or false).

Ref: https://datatables.net/examples/plug-ins/

Try the below snippet. Full text search enabled on age column.

$.fn.dataTable.ext.search.push(
    function( settings, data, dataIndex ) {
     const searchTerm = $("[type=search]").val();
     if(searchTerm){
       return data[3] === searchTerm
     }else{
       return true;
     }
    }
);

var table = $('#example').DataTable();
