Sorry for the late response.
Basically what you need to do is to assign what you want to return to a varialble and then include that variable.
if (get_post_type() == 'page') {
$faq = '{assign values for faq}';
array_push($results['pages'], array(
'title' => get_the_title(),
'link' => get_the_permalink(),
'faq' => $fag,
));
}
The problem is going finding the ones that you want because you need to search the sub fields the same way that wp searches the content.
- split the search string up into an array of words
- loop over the parent repeater
- loop over the sub repeater
- loop over the words in the search string
- test each sub field for the existence of $word
