Suele suceder que si se le da
"bFilter": false , es cierto que se quita pero resulta que queremos que siga funcionando la busqueda en el footer de la tabla.
Este es un ejemplo:
<table id="tblDatos" class="display" cellspacing="0">
<thead>
<tr>
<th width="20%">Código</th>
<th width="50%">Agrupación</th>
<th width="15%" class="no-sort"></th>
</tr>
</thead>
<tfoot>
<tr>
<th>Código</th>
<th>Agrupación</th>
<th></th>
</tr>
</tfoot>
<tbody>
<tr id="1">
<td>1</td>
<td>Pares de </td>
<td>
<button type="button" class="btn btn-default">
<span class="glyphicon glyphicon-edit" aria-hidden="true"></span>
</button>
<button type="button" class="btn btn-danger">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
</button>
</td>
</tr>
<tr id="2">
<td>2</td>
<td>Central grupal</td>
<td>
<button type="button" class="btn btn-default">
<span class="glyphicon glyphicon-edit" aria-hidden="true"></span>
</button>
<button type="button" class="btn btn-danger">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
</button>
</td>
</tr>
<tr id="3">

</button>
</td>
</tr>
@*<tr id="4">

<td>Nivel 5</td>

<button type="button" class="btn btn-default">
