How to make two queries in the same column and table in mysql

I need a little help, I'm using the mvc standard with codeigniter and I need to echo the view, searching for values from the same column from the same table. So in my view I have two input text where I would call the users name by ID, the fact that I can call one but I can not call the other, as the reference would be "name" which is the name of the column, just repeating the text of the first input, because I can not find a term that differentiates the call. Remembling that in this table "OS" has a foreign key to the table "users" and there is the auto complete function. This I am trying to do is a branch break;)

model

public function autoCompleteUsuario($q){

    $this->db->select('*');
    $this->db->limit(5);
    $this->db->like('nome', $q);
    $this->db->where('situacao',1);
    $query = $this->db->get('usuarios');
    if($query->num_rows() > 0){
        foreach ($query->result_array() as $row){
            $row_set[] = array('label'=>$row['nome'].' | Telefone: '.$row['telefone'],'id'=>$row['idUsuarios']);
        }
        echo json_encode($row_set);
    }
}

controller

    public function autoCompleteUsuario(){

    if (isset($_GET['term'])){
        $q = strtolower($_GET['term']);
        $this->os_model->autoCompleteUsuario($q);
    }

view

<input id="usuario" class="span12" type="text" name="usuario" value="<?php echo $result->nome ?>"  />
<input id="usuario2" class="span12" type="text" name="usuario2" value="<?php echo $result->nome ?>"  />
