Because nobody wants to help I've just researched vB 1.x php code and find my own way to do it.
I want to ask any expert or vB developer if I'm on the right track. I haven't tried it but I think it should work:
I will be replacing letters with:
Code:
str_replace("?","a",$string);
str_replace("?","i",$string);
...and so on
in $subject, $pagetext and $combinedwords string from following files:
misc.php [Building index part]
Code:
--------
$subject=wordsonly($subject);
$pagetext=$subject." ".wordsonly($pagetext);
$usernames=wordsonly($usernames);
--------
HERE
global.php [function indexthread($threadid) part]
Code:
--------
$subject=wordsonly($subject);
$pagetext=$subject." ".wordsonly($pagetext);
$usernames=wordsonly($usernames);
--------
HERE
search.php [MySQL Search SELECT]
Code:
HERE
--------
$searchresults=$DB_site->query("SELECT DISTINCT
threadid,
lastpost
FROM thread
WHERE visible=1 $checkforum $subjectonly $checkuser $checkdate $combinedwords
ORDER BY lastpost DESC");
--------
What do you think, will it work?
