I need to limit my search results to just blog and newPage items. But can not find info on how to do this.

All i can find is stuff telling me to amend a function in Page.php. but there is no search function in page.php. I am using 2.4.

I hope this can be done. can anyone advise please. Much appreciated

...ok i have found this.. which seems to work... but how do i limit to just blogs and newsPage items...

function results($data, $form){

$dosResults = $form->getResults();

$dosNewResults = new DataObjectSet();
foreach ($dosResults as $doResult)
{
if ( $doResult->URLSegment == "contact-us")
{
//filtered
}
else
{
//keep
$dosNewResults->push($doResult);
}
}

$data = array(
'Results' => $dosNewResults,
'Query' => $form->getSearchQuery(),
'Title' => 'Search Results'
);

$this->Query = $form->getSearchQuery();

return $this->customise($data)->renderWith(array('Page_results', 'Page'));
}
