Hello!
Changing
$search .= "{$searchand}((post_title LIKE '{$n}{$term}{$n}') OR (post_content LIKE '{$n}{$term}{$n}'))";
to:
$search .= "{$searchand}((post_title='{$term}'))";
lets you exact search in post-titles. But this case it doesn't let you terms with blank.(Finds "apple" but doesn't "apple juice")
How can i fix this?
