Can't Redirect Dynamic URLs to WordPress

I am in the process of moving a site from Joomla to WordPress, I don’t want to do any direct migration of content since there is a lot of legacy content that we do not want, a fresh start for us.

The problem is the traditional HTAccess method of redirecting URLs using a 301 redirect doesn’t seem to work with Joomla since it is a database driven CMS that uses query strings for page names. (Something about the ? is giving me problems.)

I know I need to use some sort of mod-rewrite rules but can’t seem to get my head around the concept with what I have found on about 20 other pages. Could someone please provide me with an example HTAccess file of how I would redirect this page to the new one:

Here is my current .htaccess file and it is not working, it just brings me to the homepage with a string after it instead of bringing me to the nice wordpress URL:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^/index.php?option=com_content&view=article&id=38&Itemid=64$  http://mydomain.com/insightvision/ [R=301,L]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

The rule that I am working on is this one:

RewriteRule ^/index.php?option=com_content&view=article&id=38&Itemid=64$ http://mydomain.com/insightvision/ [R=301,L]
Could someone please help me with the proper format for using mod_rewrite to redirect that URL or give me a better way of doing it?

Thanks a ton, I have been searching for literally days on this and can’t get my head around it.
