Can the content be searched after the filter was added

Hello,

I was just wondering if it’s possible for the default search in Wp to find the “new” content after a filter was added.
For example before applying the filter below, if you search the content for the word “foo” you will get the result.

function gepot($content) {
$ng = ‘foo’;
$content=str_ireplace($ng,’bar’,$content);
return $content;
}
add_filter(‘the_conten’,’gepot’);

After applying the filter, if you search for “foo” there will be an result, but if you search for ‘bar’ there will be no results.

How can I make the search to include the filter modifications?
