Search Mysql error -> Solution for drupal 5.x ?

Hello,

I am trying to make the search module work on the realease 5 of drupal.
I get a big mysql error. by reading the forum, i know that it is because my hoster doesn't allow the creation of temporary table.

In this forum subject, niosop posted a script that permits to avoid this problem.
Is there a similar script for the last realease ?

Thank you.
