Datatables multiple or filter in select

Hello I would like to filter my items in my datatable by select input. But when I filter it, datatables uses AND method. I would like to filter my items with OR.

The point is when I choose HOME and WORK filter in select input it must display me items from HOME or WORK category (not items which are in home and work category both like is now).

The HTML Code:

    <h4>Select your multiple filter</h4>
<div>
    <select id="select-category" name="categories" multiple>
        <option value="">All</option>
        <option value="Home">Home</option>
        <option value="Work">Work</option>
        <option value="City">City</option>
    </select>
</div>
<div>
    <h4>Table of items</h4>
    <table>
        <thead>
        <tr>
            <th>Id</th>
            <th>Name</th>
            <th>Category</th>
        </tr>
        </thead>
        <tbody>
            <tr><td>1</td><td>Lamp</td><td>Home</td></tr>
            <tr><td>3</td><td>Desk</td><td>Work</td></tr>
            <tr><td>2</td><td>Books</td><td>Home</td></tr>
            <tr><td>3</td><td>Cars</td><td>City</td></tr>
            <tr><td>3</td><td>Desk</td><td>Work</td></tr>
            <tr><td>3</td><td>Photocopying</td><td>Work</td></tr>
            <tr><td>3</td><td>Clip</td><td>Work</td></tr>
            <tr><td>3</td><td>Street</td><td>City</td></tr>
         </tbody>
    </table>
</div>

The JS Code:

var dataTable = $('table').dataTable();
$('#select-category').change( function () { 
    dataTable.fnFilter( $('#select-category').val(),2);
});

Here is my jsfiddle link with my example of filtering with AND, which i want to change to OR.
