Imrpove AliPlugin with AliTheme and WordPress search function

Hi guys!
I want to improve the search function of a wordpress site with AliPlugin. The products shown are completely off topic, you have to be very accurate to get what you need, if you are too accurate of course, you will get nothing.

So far I found this code in “functions.php”, does anyone know where I can find the code for the search function and fix it. There is no “search.php” page in “editor”.
[code]
$t?ext['search'] = __('Search Results for: %s', 'ali4', get_search_query());
---------------------------------------------------------------------------------
} elseif (is_search()) {
echo $before . sprintf($text['search'], get_search_query()) . $after;
} elseif (is_day()) {
echo sprintf($link, get_year_link(get_the_time('Y')), get_the_time('Y')?) . $delimiter;
?? echo sprintf($link, get_month_link(get_the_time('Y'), get_the_time('m')), get_the_time('F'?)) . $delimiter;
[/code]

I can give access to the site if necessary.

The page I need help with: [log in to see the link]
