I would like to redirect pagination of my Joomla homepage from https://example.com/index.php?start=5 to the root (https://example.com/) without impacting other pagination in website (ie: https://example.com/news.html?start=5 or https://example.com/categories.html?start=5).

I am able to redirect the https://example.com/?start=5 to https://example.com/ without impacting the rest of the pagination of the site with the following rule:

RewriteCond %QUERY_STRING ^start=([0-9]*)$ [NC]
RewriteRule ^$ https://example.com/$1? [R=301,L]

However it is impossible for me to redirect with the inclusion of index.php (https://example.com/index.php?start=5) without impacting the rest of the pagination of the site. I tried with the following rule:

RewriteCond %REQUEST_URI ^/index.php$
RewriteCond %QUERY_STRING ^start=(.*)$
RewriteRule ^index.php$ https://example.com/ [R=301,L]

but this impacts the rest of the pagination of the site like https://example.com/news.html?start=5 redirect to /.

Do you have any idea to do this kind of redirect ?

Here is my curent .htaccess :

IndexIgnore *

## Can be commented out if causes errors, see notes above.
Options +FollowSymlinks
Options -Indexes

## Mod_rewrite in use.
