            }

            if ($where != '') {
                $select->where($where);
            }

            $sql = $adapter->insertFromSelect($select,
                $this->getTable('catalogsearch/result'),
                array(),
                Varien_Db_Adapter_Interface::INSERT_ON_DUPLICATE);
            $adapter->query($sql, $bind);

            $query->setIsProcessed(1);
        }

        return $this;
    }
}

?>

Here in the function prepareResult i just added exit() but it is not working;

Please help me , Thanks in advance

As i see you are trying to rewrite the model.so you have to have rewrite the model in the following way

<models>
    <catalogsearch>
        <rewrite>
            <resource_fulltext>Sid_Newsearch_Model_Resource_Fulltext</resource_fulltext>
        </rewrite>
    </catalogsearch>
    <newsearch>
        <class>Sid_Newsearch_Model</class>
        <resourceModel>newsearch_mysql4</resourceModel>
    </newsearch>
</models>

and importantly you are trying to rewrite wrong module which doesn't exists.your class should be

Your class under Sid/Newsearch/Model/Resource/Fulltext.php should be like

class Sid_Newsearch_Model_Resource_Fulltext extends Mage_CatalogSearch_Model_Resource_Fulltext

try avoiding folder called CatalogSearch under Model.
