Wayne said this is the query:
https://vborg.vbsupport.ru/showpost....75&postcount=4
I think it would be an easy Add-on:
Search.php: Line1296
PHP Code:
$post_query_logic[] = "post.postid IN(" . implode(',', $requiredposts) . ")";
If
count() of
$requiredposts >
X prompt user to refine query.
This would stop thousands of postid's from being passed to that "IN" clause.
